Intel P4 3.00 GHz, MSI MS-7012. It's a Medion 8080XL computer.

I've downgraded to 6.2-RELEASE and the problem disappeared. When I 
upgraded, the problem was back.

I've looked at the list of files changed since RELEASE, but I don't see 
how any of the changes in sysctl.c should cause this. I know little 
about the source tree, but none of the other files changed ring a bell.

And noone else seem to be having this problem. It's a little frustrating.

Could I check-out STABLE at various dates, build world and kernel, 
install and boot, until I get the error? Is it possible? That way I 
would at least know the date of the guilty commit.
