[Bug 575392] [NEW] ksoftirqd high CPU on 10.04-LTS Server

[Ralph Forsythe]

Public bug reported:

On an HP DL380G6 running a fresh install of 10.04 LTS Server 64-bit, I
observed ksoftirqd hitting the CPU (up to 100%).  Fortunately it limited
itself to one core.  I did not see this on 9.10 Server 64-bit on the
same hardware.  I installed the mainline kernel from today
(2.6.34-999-generic) and the problem did correct itself.

I am attaching output from 'apport-bug -p linux' with the stock kernel
and bug present; obviously I cannot do the same for the mainline kernel,
but please let me know if there is any other information I can gather to
help determine what is different.

Per the request near the end of the responses in Bug #183461, I am
filing a new bug report for this issue.
