Public bug reported:
When playing video from an external ieee1394 drive with mplayer (unsure
if it occurs other times too), the video will stall at an irregular
interval. After a second or two it will start playing again.
During this time, 'top' reports ~100% CPU utilization waiting for I/O (%wa),
and the following lines are dumped in /var/log/messages:
Oct 1 23:13:42 ginger kernel: [260307.000180] ieee1394: sbp2: aborting sbp2
command
Oct 1 23:13:42 ginger kernel: [260307.000213] sd 2:0:0:0: [sdb] CDB: ATA
command pass through(16): 85 08 2e 00 00 00 00 00 00 00 00 00 00 40 a1 00

Oct 1 23:13:42 ginger kernel: [260370.000194] ieee1394: sbp2: aborting sbp2
command
Oct 1 23:13:42 ginger kernel: [260370.000221] sd 2:0:0:0: [sdb] CDB: ATA
command pass through(16): 85 08 2e 00 00 00 00 00 00 00 00 00 00 40 a1 00
This happens about once every 1-20 minutes, averaging about 4 or 5 minutes
(pretty irregular, I don't see a pattern).
Also, going back in the log there is a steady stream of these messages, even
when the machine is otherwise idle. So it is not access via mplayer, that is
simply a symptom that makes it obvious (and annoying).
The external drive is a 1TB western digital caviar green WD10EADS living
in a Macally G-S350SUA firewire 400 enclosure. I presume the ubuntu-bug
has already collected by other system information.
