pc card hangs computer with 2.6 kernel (more details)

[Samuel Sieb]

I sent this originally to the pcmcia list, but haven't seen a response yet.

My laptop freezes as soon as I insert a Linksys WPC11 card which is an
802.11b wireless card.  I don't think it's the driver since as far as I
can tell, the drivers aren't included in the kernel (it's a prism 2).  I
first tried with a 2.6.1 kernel and then upgraded to 2.6.4 but it still
acts the same.  (I'm using Fedora Core Testing, updated to latest.)

The laptop is a Compaq Presario 2190, the cardbus is:
00:0a.0 CardBus bridge: O2 Micro, Inc. OZ6912 Cardbus Controller
         Subsystem: Hewlett-Packard Company: Unknown device 0024
         Flags: bus master, stepping, slow devsel, latency 168, IRQ 11
         Memory at 80000000 (32-bit, non-prefetchable)
         Bus: primary=00, secondary=02, subordinate=05, sec-latency=176
         Memory window 0: 81000000-81100000 (prefetchable)
         Memory window 1: 10000000-103ff000
         I/O window 0: 00003000-0000307f
         I/O window 1: 00004000-000040ff
         16-bit legacy interface ports at 0001

dmesg shows:
Yenta: CardBus bridge found at 0000:00:0a.0 [103c:0024]
Yenta: ISA IRQ mask 0x0498, PCI irq 11
Socket status: 30000007

0x4d0-0x4d7
cs: IO port probe 0x0a00-0x0aff: clean.

I just noticed that it did get a message in /var/log/messages:
Apr  1 09:48:57 localhost kernel: cs: memory probe xa0000000-0xa0ffffff:
clean.
Apr  1 09:48:57 localhost cardmgr[1001]: socket 0: Intersil PRISM2 11
Mbps Wireless Adapter

That's the last thing in the log before the next startup.
If the card was already in when I booted it, then there was one more
line in the log from the next booting step before it hung.

Further probing shows that the computer is still functioning as I can 
use sysrq functions.  Using sysrq-p gives me a list that appears to 
scroll off the screen.  From the top of the screen, the first few items are:
alloc_netdev
ether_setup
orinoco_cs_hard_reset
orinoco_cs_attach
orinoco_cs_event
bind_request
kmem_cache_alloc
bind_request
ds_ioctl
get_random_bytes
arch_align_stack
mmap_top
mm_init

I have updated the laptop's bios to the latest version.  Any other 
information that would be helpful?

I had similar issues with an hp laptop which was running fedora at the
time. It turns out to be the fedora pcmcia config vs the laptop.  You
can try this /etc/pcmcia/config.opts file, originally posted by Mathieu
Lesniak (Thanks Mathieu!) in response to my issue - it forces pcmcia to
use a specific irq and memory range, and it Worked For Me (tm)

Thank you very much!  (I'm sending this wirelessly.)
It did take IRQ 10 even though it was excluded in the config file.  But 
it works, so it was either a port issue or memory issue.  I'll try to 
narrow it down if I get a chance.
