Sorry, i'm retarded, i pasted the wrong changelog line.

<[email protected]>
	[8139TOO]: Use rtnl_lock_interruptible()
	
	The 8139too thread needs to use rtnl_lock_interruptible so it can avoid
	doing the actual work once it's been kill_proc()ed on module removal
	time.
	
	Based on debugging and an earlier patch that adds a driver-private
	semaphore from Herbert Xu.

This seems to be the only patch that contains a change to the 8139too code between working and non-working code.

nothing in mm's patchset seems to have anything to cause these problems.

this is in the changefile to 2.6.11. This seems to be the real culprit. I guarantee you if this patch is reverted, there will be no problems.

Your 2.6.11 dmesg mentions the VIA IRQ fixup, but the 2.6.12 one

Can you try the attached debugging patch?  And please collect the
output of lspci, too.





I tried the attached patch and it had no effect. I also tried porting
the 2.6.11 way of handling the VIA quirk but it didn't have any effect.
I'll try a more complete port tomorrow (it was a bit of a hack this time).

2.6.11-mm4 doesn't work. So i'm guessing 2.6.11 wont work either which may be why backporting it's via fixes didn't do anything. I'm gonna try vanilla and if that by some crazy chance works, then it'll be fairly easy to see what change did it since mm has a nice Changelog.
