hey tallboy

there have been quite a few threads about 5.4 hanging, the experience on my own machines caused be to revert to 5.3.3

if left for (quite) a while normal service normally resumes, the hanging duration does seem to be random, it may not be the same fault but worth investigating

I have converted a couple of peeps to slacko and burnt them the then latest version which I think was 5.3.90 and they haven't reported any hanging issues but I only see them periodically so haven't had a chance to delve further

@ ally and SFR ..I still can't reproduce these errors!..

BUT.. I just noticed something.. both of you are using ext2 savefiles.. I always use ext4... I wonder if this is the common denominator?

I'll do some tests soon.

@ tallboy, I'll look into dvd session saving issues too

Hi mick

Had it happen to me today for first time - also an ext2 savefile (1G) - disk thrashes constantly - had to do ctrl-alt-backspace to console - xwin and all was OK again....

It is hard to get you diagnostics when the system freezes - but if we can get something from the console??

Cheers
peebee

The only thing I can suggest is if a drop to prompt stops it then you should be able to capture /tmp/xerrs.log BEFORE restarting X.
Code:
cp /tmp/xerrs.log ~
Shouldn't be hard to remember Smile

I wish puppy had a log of AUFS activity. But I guess debug needs to be turned on.

EDIT: just made 10 of SFR's "bigfiles" in a row to a pristine ext2 save, no issue Confused . It may well be a hard drive driver issue. What else do we have in common? Laptops?

EDIT: ok.. I needs some figures off you guys.. SFR, ally, 8-bit, peebee. What RAM do you have? What swap if any, and type, swapfile or swap partition?

Some reading.
Things have changed in the kernel and there seemed to be significant changes between 3.1x and 3.2x. I wonder if anyone using slacko-5.3.3.2 (an unreleased beta for 5.3.4) has experienced these issues? It's still available at my smokey01 repo, and was very close to being a release, except slackware 14.0 kicked into gear, nullifying that effort. IIRC, it shipped with k3.2.2.

hey micko

I had 5.4 ff installed on a lenovo t61 and a dell gx620, it happened on both machines

I can't remember why but I resorted to ext2 on the dell (I think I read about a conflict but of what and why I can't remember)

**EDIT - there was a bug that involved ext4 and hdd mount errors, I THINK I may have tried to use ext2 to see if it made a difference and just stuck with it

the lock-up occurred when trying to access hdd's, I always run separate partitions for the OS and data, the system would hang whilst trying to access a drive or partition, my t61 has 2 partitions on 2 drives each (ie 4 in total)

I would be able to start another ram based app but would hang like crazy on occasions opening a drive, once it finished feckin about it would be ok again, the reason and duration of the hang and interval appeared random

my knowledge to be able to trap errors is lacking and I did query a how to

I have a spreadsheet of the builds I collect and I mark those than I burn and play, the version I passed on to friends was slacko-5.3.9.5-firefox-4g, I know that it is installed on a desktop pc and a laptop (machine specs unknown) but neither has reported any issues so I suspect the issue is a change between the two

am happy to give it some more testing if I can help track errors but I will need some hand holding on what to look for

Between 5.3.9.5 and 5.4 the changes were as above...

bugfix Spanish locale jwm
.. which equates to negligible.

The problem is how the kernel handles pages. SFR is onto it.

Shame none of this showed up in testing, but then real testing begins when you release ... Laughing (@ disciple, can you add that to your "quotes" thread?)

micko

I've put a request into the users I mentioned for details, they are brand new puppy/linux users so suspect that they will be running ntfs file systems

I'll put a clean 5.4 install onto the dell again and have a bash around again to see if I can induce the error

I did run the 5.3.9.5 opera for a (short) while and didn't have any issues but did in the 5.4, can try both if you think it will help

will keep you posted

Hard disk ntfs

I notice SFR mentioned NTFS.. is that the common factor? (laptops are now out, and probably hdd drivers)

There has been reported trouble with NTFS on LQ-Slackware forum, I have been following it for awhile..

Ok, safe to say you use native Linux filesystems Cool (discounting NTFS.. lucky.. microsoft, law suit was pending..[joke] [does that cover my arse?])

^^^^^^

there my machines, sorry for confusion

my dell is a headless system so just loading 5.4 onto an ibm t21 for a bash

Smile

** EDIT - the 'friends' machInes have 5.3.9.5 ff running on a laptop with ntfs and a desktop running ext2, he has commented that the desktop 'once threw a wobbly' but couldn't be more specific as it only happened once and a long while ago

the t21 has been been running an hour or so, frugal install ext2 without problems so far......

4GB on Toshiba laptop, 2GB on Acer laptop, no swap at all.

Other things (that didn't work), I blindly tried before:
- flushing the cache before saving the session: sync && echo 3 > /proc/sys/vm/drop_caches
- disabling all cores but one in Toshiba (i3 CPU)

But...

I just ran several new tests in VirtualBox and it seems, that NTFS indeed can be the real source of the problem (apparently in my previous tests I mixed things and only tried 'Slacko-5.3.3 + ext? as home', but omitted 'Slacko-5.4 + ext? as home' combination Embarassed )

Anyway, maybe this will shed more light...

Each puppy frugally installed on home partition with pmedia=ataflash.
Each savefile's size - 2GB.
Method of testing - repeated cat /dev/zero > /initrd/pup_ro1/root/bigfileX

Results:

Slacko-5.3.3-4g:
- slackosave.2fs on NTFS partition [ ok ]

Slacko-5.3.3.2:
- slackosave.2fs on NTFS partition [ fail on the first try ]

Slacko-5.3.95 PAE:
- slackosave.2fs on NTFS parition [ fail on the first try ]

Slacko-5.4 PAE:
- slackosave.2fs on NTFS partition [ fail on the first try ]
- slackosave.4fs on NTFS partition [ fail on the first try ]
- slackosave.2fs on ext3 partition [ many tries - only one seemed to fail...unsure ]
- slackosave.4fs on ext3 partition [ many tries - no issue! ]
- slackosave.2fs on ext4 partition [ many tries - no issue! ]
- slackosave.2fs on fat32 partition [ many tries - no issue! ]
(many tries = ~10)

Although tests were done in VBox, they're showing the issue and differences between various Slackos, so I hope they're reliable enough.

Going further I tried to replace ntfs-3g (with libs) with the one taken directly from Slacko-5.3.3, as well as installing this package, but no difference after reboot, unfortunately...

Slacko-5.4 PAE + ntfs-3g from 5.3.3:
- slackosave.2fs on NTFS partition [ fail on the first try ]
- slackosave.4fs on NTFS partition [ fail on the first try ]

IIRC I tried it once also in my real environment (slackosave.2fs on defragmented NTFS home part.), but it didn't fix anything too, though Slacko-5.3.3 + slackosave.2fs on the very same, and even fragmented, partition was fine.
Is there anything else related to NTFS what has been changed since 5.3.3?

And still don't know how/why echo 1 > dirty_stuff supresses the sympthoms; I don't catch the connection... Confused

But there's a glimmer of hope at last, so I keep my fingers crossed. Very Happy

EDIT: Out of curiosity I just checked also Presice-5.4.2 (k3.2.29) on NTFS - same problem there...

Greetings!
