Full boot/run log

I'm seeing a ton of CPU soft lockups in 3.17.0-rc1-00231-g7be141d when building a kernel (make -j8). It seems to lock up hard enough that I have to hard power off.

Sorry if this is the wrong component. I guessed that this is a bug in nouveau.

Full log attached.

Comment 1 Ted Percival 2014-08-25 17:00:16 UTC

Earlier in the log I see a machine check exception

[  300.954634] mce: [Hardware Error]: Machine check events logged

Maybe this is just the result of overheating some hardware?

I didn't see the problem on my old 3.2 distro kernel (3.2.60-1+deb7u3) though.

Comment 2 Ted Percival 2014-08-27 17:06:13 UTC

I've seen this on my old 3.2 kernel too. My hardware sucks. Sorry about the noise.
