But aacraid_commit_reset.patch is not in 2.6.22-rc3 (to which you report
the issue). Does the aacraid_commit_reset.patch work to resolve this
issue all by itself in the kexec'd kernel? Or alternatively did you try
aacraid.startup_timeout=540 as one of the kernel parameters passed to
the kexec'd kernel?

The '[PATCH] aacraid: fix shutdown handler to also disable interrupts'
patch (you refer to this as patch 4) is not to be in the picture because
it will hide the root cause. I believe I have you correct in stating
that this patch (4) resolves the problem... but I expect the problem to
remain with kdump.

Sincerely -- Mark Salyzyn
