Subject: BUG: workqueue lockup
Date: Sun, 20 Mar 2016 16:41:14 +0100	[thread overview]
Message-ID: <87oaa9upgl.fsf@linux-m68k.org> (raw)

I'm getting this hangup with 4.5 in aranym:

[    2.060000] scsi host0: Atari native SCSI, io_port 0x0, n_io_port 0, base 0x0, irq 15, can_queue 8, cmd_per_lun 1, sg_tablesize 0, this_id 7, flags { }, options { REAL_DMA SUPPORT_TAGS } 
[    2.110000] blk_queue_max_segments: set to minimum 1
[   55.130000] random: nonblocking pool is initialized

[   60.270000] BUG: workqueue lockup - pool cpus=0 node=0 flags=0x0 nice=-20 stuck for 52s!
[   60.300000] Showing busy workqueues and worker pools:
[   60.310000] workqueue events: flags=0x0
[   60.340000]   pwq 0: cpus=0 node=0 flags=0x0 nice=0 active=2/256

[   60.560000] pool 2: cpus=0 node=0 flags=0x4 nice=0 hung=58s workers=2 idle: 57

I assume that this has something to do with the ncr5380 updates.

Andreas.
