Re: [gentoo-user] MCE in kernel

[Alan E. Davis]

Thank you.  I have solved the problem for now, but live in fear that there
is something untoward going in on my hardware.

Earlier on, this was intermittent.  I also wonder whether a register was set
or a cmos flag, because after I booted the Ubuntu partition, the machine did
boot with no complaint.  It hadn't been going on long, though.  Well, I
finally was able to boot using an earlier kernel with no MCE flag set, then
recompile a newer kernel without it.

I think your solution is the better one, though.

I did follow the instructions of the boot messages and installed an mce log
translation utility, but I didn't make sense of what to do with it.

Thank you again,

Alan
