Intermittently (10-20%) when booting this VIA based thin client, panics very
early in hpet_late_init.  nohpet seems to avoid the problem.  Other
distributions are reportedly not seeing this issue, so this might be a
relatively new kernel bug.

davej suggested assigning this to tglx.

The code dump at the bottom of the page doesn't match the i586 kernel at all.

8d b4 26 00 00 00 00  is a NOP [leal 0(esi),esi]

/me grumbles :)

Warren,

"Intermittently (10-20%) when booting this VIA based thin client, panics very
early in hpet_late_init."

Can you please provide the full boot log from one of the other (80-90%)
successful boots ?

Further it might be helpful, if you could capture the boot of a crash via serial
console.

Please add
 earlyprintk=serial,ttyS0,115200

to the kernel command line and connect the box to a second one with a null
modem cable. On the second box please capture the output of the kernel.

Thanks,

    tglx

I will have physical access to it again tomorrow.

More info is available in the newer bug, including full oops captures.
Why a NOP instruction could cause a divide error is a real mystery...
