What kernel modules do you have loaded when this happens?

Is there a reason for using all this non standard stuff. Can you reproduce
the problem if you don't load ALSA (I dont think alsa is prime candidate
here) and you've never loaded either vmware or xsvc or the non kernel 
pcmcia since boot ?

Obviously try with a few of them out and see - I've seen several vmware with
new apm code interactions for one , although none of the others were oopses

*smile*
Apparently, that's where you're wrong... I tried removing some
modules, until I found the one causing the trouble:

	snd-card-intel8x0

... :(


I guess it's time to check for newer version on that... :/




On another question, is there a way to find out a hardware config -
I can't switch off all individual devices in the notebook, but if I
use the prism2 driver from linux-wlan.com, I can't get the full
performance out of it - but just something like ~20kb/s throughput
in ftp  (Win2K gets more than 500kb/s)...
Some people on the linux-wlan mailing list suggested, it might be a
hardware conflict, but they couldn't give me a better idea on HOW
to locate it...
Any clue, how I could go about that?

ALSA device drivers have routines that save and restore 
the state of sound chips across suspend & resume. 
That's where I'd go a-hunting for bugs.

What happens if you use the in kernel pcmcia, and the in kernel prism 
chipset drivers ?

The in-kernel prism driver doesn't seem to work with the built-in
wireless lan. But - from what I understand from the Configure.help,
this is what I'd expect - to me it looks like, linux will support
prism2 in either PCMCIA or PLX.

2.4.17: oops in kapm-idled? (on IBM Thinkpad A30P [2653-66U])

[beh]

Trying to suspend my A30P, the screen goes black, and then about a
second later, I have this on the console (and syslog of course):

I can continue to work on the machine, but when I try to shut down
the machine, it hangs trying to unload kernel card services (or
maybe immediately AFTER unloading them -- just the last to lines
before the freeze are 'unloading kernel card services'...

Also, what used to work on an A21P, I can no longer get the machine
to hibernate...



Any ideas, what's causing this?  If more information is needed,
just let me know, what additional info I should provide...

In case you need it, I made my /usr/src/lin/ux/.config available at

	http://icemark.net/beh/dotconfig-2.4.17



Any help would be appreciated! :)
