Re-posting two patch as attachments. I'm sorry for the problems
on the
first pass. I have tested the two patches on RHEL 5.8beta (x86, x86_64),
RHEL 6.2ga (x86, x86_64), and RHEL 6.2ga with kernel 3.2 (x86, x86_64).
I haven't examined the patch, but you've done something
that has incorrectly changed the behaviour of the simple
"irq" command itself for 2.6.37 and later kernels.
Running crash-6.0.2, here is what the display should look like
for any 2.6.37-and-later kernel -- this example a 3.1.7-1.fc16
kernel:
