SubjectDying hardware?: Eeek! page_mapcount(page) went negative! (-1)
Hi,
I have a machine with Intel Desktop board D865GBF which
ran fine last 3-4 years. My last kernel was 2.6.24.7 since
May 12 2008. Last few days I get daily crashes of the kernel
with "Eeek! page_mapcount(page) went negative! (-1)" while
the stacktraces differ. I tried even 2.6.28 but again, after
one hour uptime I hit this again. I am attaching the dmesg
output. One of the other crashes I had retyped on a piece of
paper and it seemed reiserfs was involved. I could retype
it next emails if somebody is interested. It caused some
extra kernel crash but it was 2.6.24.7 kernel so maybe
nobody is interested in those traces anymore. I tried
memtest for a while and it did not find any problems, but
did not let it run more than few percent.

I have attached serial console now and maybe would manage
setup the console over firewire and somebody tells me what
to do if the crash happens again. ;-)

Thanks for any clues,
Martin
