Hello!

After switching from 2.4.20 to 2.4.21 (Debian unstable package
kernel-source-2.4.21-5), my wireless LAN PCMCIA card stopped working
when I hot-removed and reinserted it. I got these messages in
/var/log/syslog, plus a high beep on removal and a high and then a low
beep on reinsertion:

Upon removal:
Aug 29 16:00:41 SebastianL2 kernel: orinoco_lock() called with
hw_unavailable (dev=cf34b800)

Upon reinsertion:
Aug 29 16:00:44 SebastianL2 cardmgr[192]: socket 0: ZCOMAX
AirRunner/XI-300
Aug 29 16:00:44 SebastianL2 kernel: GetNextTuple(). No matching CIS
configuration, maybe you need the ignore_cis_vcc=1 parameter.
Aug 29 16:00:44 SebastianL2 kernel: orinoco_cs: GetFirstTuple: No more
items
Aug 29 16:00:45 SebastianL2 cardmgr[192]: get dev info on socket 0
failed: Resource temporarily unavailable

I looked at the changes between the two kernels, in orinoco.c,
orinoco_cs.c, and hermes.c, and it seems that quite a bit of code was
restructured. So unfortunately, I cannot narrow it down to a single
change that caused this. The attached patch fixes the problem for me,
but it is NOT a simple copy from the old driver, and it may not be
correct at all. However, it might give someone a hint about what went
wrong. Anyway, even with this patch, I still get the "orinoco_lock()
called with hw_unavailable" message when I remove the card.

Sorry if I'm posting a patch for a problem that has already been fixed
in 2.4.22. The Debian package is still at 2.4.21, and I don't know
anything about the Debian patches and why they are needed, etc. If I can
just install a kernel from kernel.org, I will do this, and try to see if
the problem is still there (I can see an item "orinoco driver update"
in the changelog, but it's not specific). Should I also install a 2.6
kernel and check?

I have attached the output of lspci -vvv and the parts of the syslog
that identify my card and show the problem. The controller is this entry
in lspci.txt:
00:08.0 CardBus bridge: O2 Micro, Inc. OZ6912 Cardbus Controller

Here is the output of ver_linux:

Hopefully someone can find the true cause of the problem. Good luck.
