Subject: [PATCH] atiixp: Old drivers/ide layer driver for the ATIIXP hang fix
X-Git-Tag: v2.6.20-rc4~70

[PATCH] atiixp: Old drivers/ide layer driver for the ATIIXP hang fix

When the old IDE layer calls into methods in the driver during error
handling it is essentially random whether ide_lock is already held.  This
causes a deadlock in the atiixp driver which also uses ide_lock internally
for locking.

Switch to a private lock instead.
