SubjectMachine Check Exception - bluesmoke.c dump in 2.2.17

Hi,

I noticed some MCE dumps getting mailed to the list in September. From
Alan Cox's comments I gathered that he was looking for similar dumps [at
least then]. My workstation produced one yesterday and I hope this is
still relevant info. This machine has seen some moderate to heavy use for
a few months now and this is the first time this [MCE] has happened. We
have, however, experienced two spontaneous and unexplained reboots.

I am not subscribed to the list, so send me a personal mail if you require
more information [ I'll check the list regularly though ]. The kernel is
an out-of-the-box 2.2.17. I also note that the other people normally
include register dumps. Mine didn't produce any of that, just the MCE
line.

Thanks,
gerhard
