Rebooted my home server into a new kernel and got a hard system lockup and a bunch of "kernel: BUG: scheduling while atomic" in /var/log/messages. The culprits seem to be nvidia-352.30 drivers from elrepo. Downgrading to 352.21 solved the problem.
which centos version?
which kernel?
which nvidia card?
what is bug report number?
CentOS 6.6, fully updated. This is not a kernel problem. The system freezes with both kernel-2.6.32-504.23.4.el6.x86_64 and kernel-2.6.32-504.30.3.el6.x86_64. GPU: GeForce GTX 650. No bug has been filed yet.
