Is this reproducable? Have you tested your memory lately?
I didn't try to reproduce it - obviously. Don't wanna lose my data ... My box was running 2.6.9-gentoo-r9 before and i switched back to it after the 2.6.10-r6 tryout. I'll check my memory this night with memtest and will post the result here, but i never had problems before like this so i think the memory is fine.
It would also be useful if you could try 2.6.11
2.6.11-r3 worked like a charm, no problems regarding this issue.
Great, thanks
