2.6.10-rc2 and x86_64; spontaneous reboots

[David Ford]

Is anyone else experiencing spontaneous reboots within a few minutes of 
bootup?  (If the system survives past the first 10 minutes, it stays up 
for a long time, but it reliably does an instant reboot with no panic or 
other indication a good 9 out of 10 times.  The system is purely idle, 
nothing going on.  memtest86+ runs for hours with no failures.

Do the restarts occur exactly 5 minutes after bootup? That would 
indicate a problem with jiffies overflow. Probably some buggy driver.

Oddly, yes.  Or almost yes since I haven't measured it exactly.  The 
typical reboot is right around five minutes of uptime.  The three times 
that I did watch /proc/uptime, right around the 2nd column going to 300 
seconds is when it rebooted.

Well, could you send here your .config ? Do you have some strange hardware?

PS: Please don't top-post. And the challenge-response mail filter is 
pretty annoying.

[David Ford sent me some file slightly resembling .config]

Hello David,

Could you first try to completely disable CONFIG_I2C and see if the 
kernel then survives the 5 minutes?
