Hello everybody,

I get an OOPS in proc_get_inode.
It shows with the sa (sadc) processes hanging in D state and the /proc/net 
directory inaccessible - every ls in there hangs in D too.

This is a dual P III 1GHz. Linux 2.4.19pre1 SMP.


I can't say for sure just now but it seem to happen on load OR unload of 
modules - which links this oops to 
	http://lkml.org/archive/2000/10/2/110/index.html
Does anybody can tell me about this oops or what informations are needed?


To track the problem down I already did a 
	while true
	do
		ls -la  ; cat dev ;	cat sockstat
	done
in one console and
	modprobe -a -k \* ; rmmod -a
in another.
But this problem does not always show up.
It MAY be the 8390 module as this is the last in syslog before the oops.

Every help is appreciated!


Regards,

Phil
