Bug#799250: linux-image-4.1.0-2-amd64: sporadic freezes overnight
More info:
This happened three more times, the last of which I was actually
using the computer (as opposed to screensaver engaged and me afk).
I noticed, after reboot, that there was lots of I/O wait (three
or even all for CPUs) and extreme lag in starting new xterms or
other applications for quite a while, although neither dmesg nor
/proc/mdstat showed any reason for it (no resync active, etc).
I did not manage to catch which programs were in D state in top,
though.
I’m trying now with linux-image-4.1.0-1-amd64:amd64 (= 4.1.3-1)
which already looks better (not the I/O(?) wait after booting,
except once during fsck of a BSD VM, and much shorter then).
bye,
