Subject: SCHED_FIFO task blocks magic sysrq
Date: Tue, 03 Jul 2001 18:11:12 -0400	[thread overview]
Message-ID: <3B424300.9D804101@dm.ultramaster.com> (raw)

It seems like the sysrq code can get starved by a SCHED_FIFO task.  I
learned this by having an accidentally runaway SCHED_FIFO task which
locked up my system.  No SAK, no sync, no unmount, no reboot.  Big Red
Button.
