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
# 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: socket 1: Linksys EtherFast LANmodem 56k
cardmgr: executing: 'modprobe pcnet_cs'
cardmgr: 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: 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
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):
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.
