Subject: RE: aic7xxx driver schedules() while holding spinlock
Date: Thu, 3 Jul 2003 16:42:16 -0400 [thread overview]
Message-ID: <001b01c341a3$97af0410$e0019d89@cybernetics.com> (raw)
In-Reply-To: <Pine.LNX.4.44L0.0307031618140.779-100000@ida.rowland.org>
While on the subject, a while ago I discovered that sym53c8xx_2 in 2.4.x
holds a spinlock (io_request_lock) while calling ioremap() and
iounmap(), which can lead to deadlock on certain hardware. If anyone is
doing a driver audit, it might be worth checking for this in other
drivers too.
