Subject: [git patches] boot fix for 2.6.33 for parisc
Date: Wed, 24 Feb 2010 17:36:23 +0000 [thread overview]
Message-ID: <20100224173623.GA21614@hera.kernel.org> (raw)
Hi Linus, please pull the following change for parisc to fix and issue
which prevents Linux from booting. (Short summary: PCI CLS was being set
from the default by the PCI layer *after* fixups, which meant sym2
fixups had an unset PCI CLS, which meant we couldn't find the root
disk.)
regards, Kyle
