Subject: [OOPS] -git8,9: NULL pointer dereference in mptspi_dv_renegotiate_work
Date: Thu, 28 Sep 2006 13:25:48 -0700 [thread overview]
Message-ID: <20060928202548.GO12968@osdl.org> (raw)
Apologies if this has already been reported; I didn't spot it on the
list. We've noticed an Oops on AMD64 when running linux-2.6.18-git8 and
-git9, but not -git7:
mptbase: Initiating ioc0 recovery
