Solution for PCs needing "nopcmcia" to boot [TESTS FINISHED]

#1 Post by pakt »

Searching the net showed that the problem with PCs freezing during PCMCIA probing is not uncommon. This affected several PC brands and popular Linux distros.

The common denominator appears to be a bug in cs IO port probing. It reports that I/O port range 0x800-0x80f is available when it is actually taken by some device, so cardmgr freezes on start.

The solution is simple:

Open /etc/pcmcia/config.opts in an editor and change the first line:
include ... 0x800-0x8ff... to
include ... 0x810-0x8ff.
This worked on my Acer 6291 laptop. It now boots without having to use the boot option "nopcmcia".

Those of you that reported having to use "nopcmcia" to boot, please try this fix. Both the Ubuntu and Toshiba support sites recommended this fix so it shouldn't do any harm.

Please report your success or failure in this thread ;)

If this solves the PCMCIA freeze problem, Barry can include the fix in Puppy 3.00

As i'd patched all my other puppy isos to add nocpmcia as a boot parm, I downloaded and burned a brand new 2,17,1 and tried booting from it -- it froze as usual.

So booted ram-only with nopcmcia, then modified config.opts as suggested and created a pup_save, then rebooted off cd without any parms -- it has come up with no problems.

Thanks for this pakt, so far so good on my Acer 5612wlmi

PS 2.17 looks very smooth and feels very quick but still needs a manual modprobe hda_snd_intel to get it barking ... but that's for another thread

Excellent ... works on my Acer 5570Z loading from a USB2 flash drive with Puppy 216EZ and an upgraded 213 to 216 copy. Both copies run but I haven't tested anything that is pcmcia yet .... I think I have an old 14.4 modem somewhere.

Thanks
