My Dualcore AMD x86-64 desktop has been a little bit unstable as long as I
remember, but at last I had enough willpower to enable netconsole to see
if anything was reported after a lockup. For some reason these
BUG messages made now their way to local log file too.

Thanks for reporting.
Either you have an active page on the inactive list, or your hardware has
flipped a bit in page->flags. I was going to say the latter is more likely,
however -- AFAIKS, the first oops should cause that page to be lost from the
LRU list, so the second oops shouldn't happen if the flip a single bad bit,
and should be pretty unlikely if it is a random error.
Still, anything explainable by a single bit flip is worth running memtest86+
overnight for.

Thanks, I thought I had run memtest86 long enough when I bought the
system, but now it found one stuck bit almost immediately.

No problem. Thanks anyway for testing and reporting.
