Comment # 25
on bug 864430
from H Harun
I just patched all my openSuSE 13.1 (251 machines all together) to kernel
3.11.10-29 and the last couple of days, 5 of them generate "CPU stuck" error
below. All machines using nfsv3. Once a machine generate this error, the
machine will NOT be usable. You cannot use the console, when you try to ssh,
it will hang after you enter your password. The machine then needs a power
cycled.
Below is the log.
