Date: Tue, 30 Dec 2008 17:40:04 +0100 From: Martin MOKREJŠ <mokrejsm@...osome.natur.cuni.cz> To: LKML <linux-kernel@...r.kernel.org> Subject: Dying 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 P.S.: Please Cc: me in replies.
