My system keeps crashing on me, and quite often this DMA_PUSHER INVALID_CMD is
the last line in ther kernel log. I also had one X lockup, where I could ssh
into the machine and see a message in the log as well. Trying to reboot the
system I got a number of "failed to idle channel" messages I'm attaching the
log for that.

Today I got a crash without log message, but perhaps the machine was simply
unable to flush the log. I triggered that by launching flightgear. Since that's
the first time I launched flightgear, I guess this bug here makes that package
unusable for me, which is very sad.

I'm still willing to help fix this, but I'll need instructions as I wrote in
comment #14. If there is any other way to help, let me know.
