About a week ago I started receiving the following message: "Uhhuh. NMI received for unknown reason b0 on CPU 0." Power cycling the box was the only way to get out of it. At first I thought it was hardware problem, but memtest86 returned no errors. Every time this happened the following message was logged: "kernel: end_request: I/O error, dev fd0, sector 0" I grep'ed /var/log/* for the same time stamp of the above message and found matches in pm-suspend.log: Initial commandline parameters: Sat Sep 5 03:35:12 PDT 2009: Running hooks for hibernate. /usr/lib/pm-utils/sleep.d/00auto-quirk hibernate hibernate: Adding quirks from HAL: --quirk-dpms-on --quirk-dpms-suspend --quirk-vbe-post --quirk-vbemode-restore --quirk-vbestate-restore --quirk-vga-mode-3 success. /usr/lib/pm-utils/sleep.d/00logging hibernate hibernate: Linux xeon 2.6.30.5-32.fc11.i586 #1 SMP Mon Aug 17 16:21:07 EDT 2009 i686 i686 i386 GNU/Linux Module Size Used by fuse 55260 2 autofs4 23788 3 sunrpc 171072 1 nf_conntrack_netbios_ns 2204 0 ip6t_REJECT 4692 2 ip6t_ipv6header 1948 2 nf_conntrack_ipv6 18828 14 ip6table_filter 3340 1 ip6_tables 11664 2 ip6t_ipv6header,ip6table_filter ipv6 258416 56 ip6t_REJECT,nf_conntrack_ipv6 p4_clockmod 4592 1 dm_multipath 15056 0 raid1 20140 1 ppdev 6848 0 snd_intel8x0 29700 3 snd_ac97_codec 100312 1 snd_intel8x0 nvidia 7087776 24 ac97_bus 1564 1 snd_ac97_codec snd_pcm 69240 3 snd_intel8x0,snd_ac97_codec snd_timer 19404 1 snd_pcm snd 55104 9 snd_intel8x0,snd_ac97_codec,snd_pcm,snd_timer pcspkr 2380 0 serio_raw 5552 0 soundcore 5920 1 snd parport_pc 23744 0 parport 31204 2 ppdev,parport_pc snd_page_alloc 8244 2 snd_intel8x0,snd_pcm tg3 96900 0 i2c_i801 10676 0 iTCO_wdt 10872 0 iTCO_vendor_support 2976 1 iTCO_wdt floppy 50300 0 i2c_core 27040 2 nvidia,i2c_i801 mptspi 16724 2 mptscsih 28592 1 mptspi mptbase 67620 2 mptspi,mptscsih scsi_transport_spi 20516 1 mptspi total used free shared buffers cached Mem: 2062148 1924060 138088 0 254972 1053972 -/+ buffers/cache: 615116 1447032 Swap: 0 0 0 success. /usr/lib/pm-utils/sleep.d/00powersave hibernate hibernate: success. /usr/lib/pm-utils/sleep.d/01grub hibernate hibernate: success. /usr/lib/pm-utils/sleep.d/49bluetooth hibernate hibernate: not applicable. /usr/lib/pm-utils/sleep.d/55NetworkManager hibernate hibernate: success. /usr/lib/pm-utils/sleep.d/56atd hibernate hibernate: success. /usr/lib/pm-utils/sleep.d/56dhclient hibernate hibernate: success. /usr/lib/pm-utils/sleep.d/75modules hibernate hibernate: not applicable. /usr/lib/pm-utils/sleep.d/90clock hibernate hibernate: not applicable. /usr/lib/pm-utils/sleep.d/94cpufreq hibernate hibernate: success. /usr/lib/pm-utils/sleep.d/95led hibernate hibernate: not applicable. /usr/lib/pm-utils/sleep.d/95packagekit hibernate hibernate: success. /usr/lib/pm-utils/sleep.d/98smart-kernel-video hibernate hibernate: success. /usr/lib/pm-utils/sleep.d/99hd-apm-restore.hook hibernate hibernate: Advanced Power Management not supported by device sdb.

Sat Sep 5 03:35:14 PDT 2009: performing hibernate The log says the disks are not hibernating correctly. I updated Gnome Power Manager a day or two before I saw the first NMI message. It would be good to get to the root cause, but at this point a work around would be great - selecting "never" in Gnome Power Manager does not fix this. Which kernel boot parameters do set in grub to completely disable hibernate? This is happening with kernel 2.6.30.5-32.fc11.i586.
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
