Letting the system continue running after filing the bug report, I
notice these two lines added to the end of dmesg:
[81531.800850] ACPI Warning: Incorrect checksum in table [iEIT] - 0x5C, should be 0x51 (20100428/tbutils-314)
[81531.801227] ACPI Warning: Incorrect checksum in table [iEIT] - 0x5C, should be 0x51 (20100428/tbutils-314)
** Description changed:
OOPS on maverick with stock kernel.
I was listening to internet radio, it quit playing and I could not get
the player to restart. Looked in dmesg and saw this oops report; I had
been tailing dmesg in an xterm and roughly correlate when this oops
happened to when the music quit.

[Background]
- Since upgrading to maverick last week, I've noticed this machine has system lockups up to 2-3 times a day.
+ Since upgrading to maverick last week, I've noticed this machine has system lockups up to 2-3 times a day. So far, the freezes have only occurred while I was using the machine (not while it was idle), particularly when playing an OpenGL-utilizing game.
I've also periodically seen short (1-sec) display blanking, usually
occurring only on one of the two monitors (and usually but not always
- the monitor that has graphics changes.)
+ the monitor that has graphics changes.) At least twice, I saw a
+ repeated sequence of blankings, followed by a freeze. One of these two
+ times I also noticed the audio change from music to making some odd
+ (feedback-like) noises immediately prior to freezing.
- This
+ My suspicion is that perhaps the OOPS, periodic freezes, and screen
+ blanking behaviors are all related. Indeed, I also noticed 2-3 screen
+ blankings prior to the sound going out, and have had several more
+ blankings while filling out this bug report. (OTOH, I've seen blankings
+ before with these monitors before upgrading, just not with such
+ frequency.)
+
+ This particular hardware is a test box from Intel which I've been using
+ this past year mainly for builds and testing, and had proven to be solid
+ as a rock. However, I hadn't tested dual-head or audio prior to the
+ upgrade so can't be 100% certain it's a regression, as opposed to just
+ incomplete hardware support or something.
