Subject: sym2 oops in 2.6.9-rc2-BK
Date: Tue, 28 Sep 2004 23:58:26 +1000	[thread overview]
Message-ID: <20040928135826.GA3373@krispykreme.ozlabs.ibm.com> (raw)


Hi,

Ive got a 2.6.9-rc2-bk tree from about September 16 which exploded in
sym_prepare_nego. It turns out sdev is NULL, and scsi_device_dt(sdev)
causes the trouble.

A few lines above there is a check for sdev != NULL, so assuming it is
valid to be NULL add a check before scsi_device_dt() too.

Anton
