Hello,
I have an Intel® Server Board S5500BC which started to cause problems during
boot, mainly with the e1000e driver, raising the server without any NIC/s. A
reboot ususally recovers the NIC/s.
The following trace is seen from the unit boot, showing an inconsistent
problem while trying to load the e1000e driver.
Looking at the sources, it looks like it is stuck in a critical section. But
I frankly do not understand how it is possible, as there is no real reason
for it to hang on the mutex lock.
At the moment, except memory curroption/leak I cannot think of anything
else... I see it on several machines, so I assume it is not a specific HW
problem.
I will apriciate if someone could point me into some direction.
Note, the pasted message below repeats in a loop, always hangling on the
same lock. In addition, these units also hang from time to time on initramfs
shell, with an avarage of 3 times less frequent than the NIC issue.
I'm using the following Kernel version:
Linux version 2.6.32-29-generic-pae (buildd@roseapple) (gcc version 4.4.3
(Ubuntu 4.4.3-4ubuntu5) ) #58-Ubuntu SMP Fri Feb 11 19:15:25 UTC 2011
(Ubuntu 2.6.32-29.58-generic-pae 2.6.32.28+drm33.13)
Thanks,
Edy.
