I experience system freezes on Ubuntu 12.04 when working with eclipse
(when switching between open files using tabs). This is reproducible on
my system. I have not yet observed this behaviour at other tasks /
programs; system runs fine except for that (including video games and
watching videos).
The last thing I notice in kernel log (when freeze) is this:
kernel: [ 2560.052581] [drm:gen6_sanitize_pm] *ERROR* Power management
discrepancy: GEN6_RP_INTERRUPT_LIMITS expected 00070000, was 16000000
Computer is a brand new Lenovo B590 with Intel video (module i915 is
used). Since I have it only a few weeks, I cannot tell if this error
already occurred in previous Ubuntu releases or not.
I have all (and only) official Ubuntu updates installed, currently
3.2.0-54-generic #82-Ubuntu SMP Tue Sep 10 20:08:42 UTC 2013 x86_64
x86_64 x86_64 GNU/Linux.
I suspect that the Eclipse IDE requests some special stuff from video
driver which then crashes. Obviously it should not be possible for
userspace to crash the kernel, so this should also be considered a
security problem.
More details to come, I'd be glad to provide more data.
