Package: src:linux
Version: 3.5.2-1~experimental.1
Severity: grave
Justification: causes non-serious data loss
Dear Maintainer,
Since returning to NZ and reinstalling Debian unstable on my computer in March
this year, I have had issues with
my computer freezing about once per week. This seems to be due to both CPUs
freezing, but not at the same time --
I get error messages about stuck CPUs prior to the computer becoming completely
unusable. This is a data loss issue
for me because the only fix I can use to get the computer working again is a
reset, which can mean that cached
data from recent work is not written to the hard drive. The issue had not
previously impacted my desktop work too much,
as long as any programs that I ran saved their state at reasonably frequent
intervals or did not take more than a
day or so to run. I have since replaced the computer with another system at my
work, but now use the sytem at home
as an experimental web server, where intermittent, difficult-to-repeat CPU
freezes are a bit more of a problem for me.
This was a system that had been kept in storage for about a year while I was in
Germany, so I thought it might
have been a hardware problem, but I've always had the thought of a software bug
in the back of my head (this is
my first report of the issue). Prior to my trip to Germany, I had been running
Debian unstable fine (within expected
limits) for about 5 years (although the installation was 32-bit rather than the
current 64-bit version). I have tried
to update the kernels in an attempt to fix this problem, to no avail. The
current kernel is from experimental,
because I am always hoping that the next version will fix the problem.
There does not seem to be any relationship between anything obvious and the CPU
freezes. Considering it might be
a hardware issue, I gave the computer a good clean with no change in behaviour.
A brief memcheck (one pass) seemed
fine. It is possible that the issue ocurrs more frequently under high load, but
that might just be because I'm more
likely to be around the computer when it's doing more things at once.
An example dump from syslog is shown below:
