R815 machine checks under jessie
Jerry - I had some communication with you about a year ago.
I have four R815s. They have been running Debian since purchase about 6 years
ago. I upgraded from wheezy to jessie about a year ago. For the past year,
all four exhibit sporadic machine checks that cause them to crash. I never
observed this before the upgrade. I upgraded a dozen T5500s and four C6145s
from wheezy to jessie at the same time and none of them exhibit this problem.
This appears to be specific to the R815s and jessie.
The R815s run jessie fine. Just that they machine check about a week or a few
weeks after reboot. I read on the net that this may be related to fan speed or
temperature. But I can't find that web page now.
Suggestions on how I might fix this?
Thanks,
Jeff (http://engineering.purdue.edu/~qobi)
