Subject: NUMA-Q breakage 6/7 lack of bio splitting workaround
Date: Fri, 12 Jul 2002 15:40:09 -0700 [thread overview]
Message-ID: <20020712224009.GD25360@holomorphy.com> (raw)
NUMA-Q's have qlogicisp adapters for their boot bays. Until the block
I/O issue is resolved, they can't boot. I've bugged you about this
before, but for completeness' sake, here it is.
Workaround (due to akpm) below.
Cheers,
Bill
