Description Paul Meighan 2002-11-11 17:26:12 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)

Description of problem:
Initially, starting pcmcia caused my laptop (IBM Thinkpad 600) to completely 
lock up. I was able to make some progress when I made this change 
in /etc/pcmcia/config.opts:

# diff /etc/pcmcia/config.opts /etc/pcmcia/config.opt.orig
#include port 0x100-0x4ff
>include port 0xc00-0xcff

Commenting out the include of port 0x100-0x4ff changes the behavior. Now 
instead of locking up the computer when I try and start pcmcia, it acts like 
it's starting, (beeps appropriately) but fails with these errors in dmesg:

divert: allocating divert_blk for eth0
eth0: pcnet_reset_8390() did not complete.
pcnet_cs: unable to read hardware net address for io base 0xa20
divert: freeing divert_blk for eth0

in messages it also complains:

cardmgr[764]: socket 1: Linksys EtherFast LANmodem 56k
cardmgr[764]: executing: 'modprobe pcnet_cs'
cardmgr[764]: executing: 'modprobe serial_cs'
kernel: eth0: pcnet_reset_8390() did not complete.
kernel: pcnet_cs: unable to read hardware net address for io base 0xa20
cardmgr[764]: get dev info on socket 1 failed: No such device

Linux knows the card is there at this point, but neither the modem nor eth0 
actually work.

I tried upgrading card services to no avail. (no change in behavior at all.) 
I'm running 3.2.3 now.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install Redat 8.0 (on IBM Thinkpad 600 with pcmlm56 pc card)
2. run /etc/rc.d/init.d/pcmcia start

I run Red Hat 8.0 on the IBM TP600 as well as it happens. The PCMCIA howto has
some notes on the thinkpad regions to exclude.
