I've just kept machine working on duplicating this issue whole morning
today. I've completely loaded it and keep it working 100% loaded with
gcc compilation and ghc compilation to make sure it's really heated to
the max level. And I've not been able to duplicate it so my former idea
that this might be from overheating goes into trash. Thanks for your
kind notification. I've also already started to suspect ghc, but indeed,
it's hard to duplicate this issue.

Indeed, all other cases are already ruled out now. BTW: what's a ticket
number of this issue?

Thanks,
