Fortunately, I was able to observe that this is not a regression from
3.2.0-23 to 3.2.0-24. We have a server which is running 3.2.0-23 which
output the same errors. Here is the output in dmesg:
[988120.548020] INFO: rcu_bh detected stall on CPU 1 (t=0 jiffies)

Hi Joseph,
Unfortunately, on all three systems that we observed this issue, there
was no obvious reason for why it happened and hence we have no way of
reproducing the problem. We are able to test with the latest upstream
kernel only on one of the machines as only one of them is not mission-

>From your logs, I can seen this occurs after a long set of ATA errors:
[114134.155011] ata7.00: exception Emask 0x0 SAct 0x0 SErr 0x240 action 0x0
[114134.155134] ata7.00: BMDMA2 stat 0x68652201
[114134.155208] ata7: SError: { Handshk UnrecFIS }
[114134.155276] ata7.00: failed command: WRITE
Do you have some type of test case to reproduce this issue? If so, it
would be good to know if this is a regression from 3.2.0-23 or not.
Also, would it be possible for you to test the latest upstream kernel?
Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the
latest v3.4kerne
