My system seems to have become really unstable lately with applications crashing with sigsev or the whole system freezing (even at runlevel 3 in bash) I'm running: Linux espresso 2.6.5-7.111-default #1 Wed Oct 13 15:45:13 UTC 2004 x86_64 x86_64 x86_64 GNU/Linux I have seen errors like the one below on the console quite a few time recently. bad page state at free_hot_cold_page (in process 'artsd', page 0000010001b6f1b8) flags:0x20100014 mapping:000001003df96630 mapped:0 count:0 private:0x00000000 Backtrace: Call Trace:<ffffffff80159788>{bad_page+120} <ffffffff80159b2f>{free_hot_cold_page+127} <ffffffff801634f8>{unmap_page_range+712} <ffffffff801636f0>{unmap_vmas+320} <ffffffff8016622a>{exit_mmap+106} <ffffffff80133964>{mmput+68} <ffffffff801379d1>{do_exit+497} <ffffffff801382f9>{do_group_exit+169} <ffffffff801103a4>{system_call+124} Trying to fix it up, but a reboot is needed heres a few more examples: Oct 25 12:23:58 espresso kernel: Bad page state at free_hot_cold_page (in process 'yast2', page 0000010001d6ab78) Oct 25 12:24:56 espresso kernel: Bad page state at free_hot_cold_page (in process 'sh', page 0000010001ceeaf8) Oct 25 15:34:52 espresso kernel: Bad page state at free_hot_cold_page (in process 'firefox-bin', page 00000100010cc538) Oct 25 15:34:53 espresso kernel: Bad page state at free_hot_cold_page (in process 'X', page 0000010001d0b8f8) Oct 29 21:41:24 espresso kernel: Bad page state at free_hot_cold_page (in process 'online_update', page 000001000184f158) Oct 31 13:32:47 espresso kernel: Bad page state at free_hot_cold_page (in process 'K03cron', page 0000010001d4f7b8) Oct 31 13:53:54 espresso kernel: Bad page state at free_hot_cold_page (in process 'artsd', page 0000010001b6f1b8) Does this look like a hardware problem or is it something I've broken? I should be getting 9.2 in a few days :) so do I just give up on this install or does it look fixable. I've not seen the same issues on the 32bit install on the same box but then I don't use it much. Any ideas? Ed
