Hi folks,
I just noticed the following couple lines in my kernel log for Linux
3.4.2:
Jun 20 14:57:54 emergent kernel: BUG: Bad rss-counter state mm:ffff88000ff1f400 idx:1 val:-2
Jun 20 14:57:54 emergent kernel: BUG: Bad rss-counter state mm:ffff88000ff1f400 idx:2 val:2
I have no idea what these messages mean, nor what I was doing exactly
at 14:57:54 today, nor whether they've been fixed in newer kernels.
Regardless, they appear to be telling me that there's a kernel problem
since they contain the word "BUG", so I figured I had better report them
nonetheless. Other than the fact that these messages were printed, the
system is operating normally.
This happened about a week after bootup, so it's probably not easy to
reproduce.
Let me know if you need any more info,

Ah, and it appears to have been merged by Linus yesterday.
