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 126.96.36.199 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
I've booted up with maxcpus=1 and noapic and the problem remains.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot up box
Actual Results: Box reboots without warning or logging anything
Expected Results: Box ought to have been stable ;-)
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
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?
