Description Andrew Jones 2010-09-23 07:52:09 UTC

From Stephen Smalley

"I found that the tpm_tis driver in the kernel package (just running non-xen linux) immediately complains about IRQ mismatches, and that was fixed upstream by: commit 7917ff9a4cefd0500aa4a1b1942da96dbce6999f"

Hey Andrew,

can you point me to a machine that shows this behaviour?

I don't know of any. Stephen can you tell Stefan what type of hardware is giving you these complaints?

Comment 4 Stephen Smalley 2010-09-30 18:34:48 UTC

I was testing on a Dell Latitude D620.  But I think this is a common issue, and the fix is upstream as I noted.

I was able to successful test that 7917ff9a4cefd0500aa4a1b1942da96dbce6999f fixes the problem. Will take care of it.

Comment 10 Jarod Wilson 2010-10-19 18:53:48 UTC

in kernel-2.6.18-228.el5
You can download this test kernel (or newer) from http://people.redhat.com/jwilson/el5

Detailed testing feedback is always welcomed.
