From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) Description of problem: I've not been running fedora kernels for a while but today fired up the latest one in -devel (entire system is up to date with devel). I usually run -mm and vanilla kernel.org kernels. The system boots up normally, and all looks well, however 5-10 seconds after the system reaches it's final runlevel 3 and the login prompt appears, it falls over and returns to the bios screen. This problem had not occurred with any other kernel I have ever tried, including the vanilla 2.6.8.1 from kernel.org. The box passed with 100% on memtest, on a 4 hour run. It is an Intel P4-2.8, with HT enabled, on a Gigabyte 8IPE1000-Pro2 board (intel 865 chipset). I am running reiserfs on a raid1 set of disks. I've booted up with maxcpus=1 and noapic and the problem remains. Version-Release number of selected component (if applicable): 2.6.8-1.584 How reproducible: Always Steps to Reproduce: 1. Boot up box Actual Results: Box reboots without warning or logging anything in /var/log/messages Expected Results: Box ought to have been stable ;-) Additional info: Box has latest BIOS installed, kernel is not tainted. I am not overclocking the system.
Kernel is the smp version.
Box also spontaneously reboots even if only run up to single user mode :(
can you see if the i810_tco module is getting loaded? that's the hardware watchdog your system has.....
Yep, the i8xx_tco module is there...
if you remove it (say from the filesystem) the reboots should go away..
I've had 14 minutes of uptime with that kernel now, I never got anywhere near that before, so looks pretty likely that is the problem. What is the workaround for this, is it to edit modprobe.conf?
