Hi,
2.6.10 and earlier worked fine for me, apart from the occasional failure I can
somewhat live with, but 2.6.11 seems to have horribly broken the combination
between suspend (disk|ram) and PCMCIA. 2.6.9 and earlier is very flaky WRT
S3, S4 via suspend2 is working fine for me for ages, apart from occasional
driver problems.
Unloading orincoco_cs and then yenta_socket hangs rmmod in D state. If I then
send the machine to S3 it will hang on resume, right after having switched
the display back on, leaving me with funny colors and a not-responding system
(no SYSRQ, no reaction on CAPS lock, whatsoever).
Both, S3 and S4 work fine without the PCMCIA adapter inserted. My suspend
scripts unload PCMCIA and related stuff and are supposed to stop cardmgr. (I
have problems resuming without the PCMCIA card plugged in when I suspended
with it inserted, making swsusp hang about at the end of resuming with
"orinoco_lock() called with hw_unavailable (dev=de08f800)".) It does seem to
work if I leave the modules alone and just initiating S3, but then I'd better
not remove the card in the meantime.
Hardware is a Asus L3800C notebook and a Lucent Silver PCMCIA WLAN adapter.
Here's the output you're probably after (please let me know if it's
incomplete):

I am getting this oops if I try to rmmod -f orinoco_cs while the card is
inserted, the problem seems to boil down to that (This oops obviously renders
the PCMCIA card unusable until I reboot):

Replugging the adapter results in a kernel panic.
Is this info useful enough for someone to have a closer look at it? If not,
can I provide more? If you want me to try something else, please also drop me
an email.
On a different note, is there a split out version of the PCMCIA hotplug stuff
recently merged into -mm? I'd like to try it and see if it fixes my issues,
but I'd rather not introduce too much new deltas.
I've put my config and dmesg from a clean boot here:
http://vizzzion.org/~sebas/tmp/lkml/config.txt
http://vizzzion.org/~sebas/tmp/lkml/dmesg.txt
CC:'ing me on replies would be cool, although I'm trying to keep up with LKML.
Thanks in advance for having a look at it,
sebas
