Subject: [PATCH 5/6] mpt fusion - abort of board reset leaves port dead requiring reboot
Date: Thu, 18 May 2006 15:00:32 -0500 [thread overview]
Message-ID: <446CD260.7040703@sgi.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 382 bytes --]
The driver uses msleep_interruptible() in the code path responsible
for resetting the card's ports via the lsiutil command. If a
<ctrl-c> is received during the reset it can leave a port in such
a state that the only way to regain its use is to reboot the system.
Changing from msleep_interruptible() to msleep() corrects the problem.
