Subject: In place kexec
Date: Wed, 28 Jul 2010 14:57:01 -0700	[thread overview]
Message-ID: <4C50A7AD.8040902@zytor.com> (raw)

We are getting a claim that the qla driver corrupts memory after a
kexec, apparently due to a DMA engine left running in the before-kernel.

For an in-place kexec (as opposed to a crash dump kexec, where we switch
into dedicated memory), what shutdown paths get executed?
