I have tracked down the source of the sbp2 passthrough commands. ps ax -F during 'normal' operation, then again during a stall, then see what's different: root 5313 1017 0 459 480 0 21:35 ? S 0:00 /bin/sh -c /etc/acpi/power.sh root 5314 5313 0 459 508 0 21:35 ? S 0:00 /bin/sh /etc/acpi/power.sh root 5319 5314 0 459 564 0 21:35 ? S 0:00 /bin/sh /usr/sbin/pm-powersave root 5336 5319 0 459 552 0 21:35 ? S 0:00 /bin/sh /usr/lib/pm-utils/power.d/95hdparm-apm false root 5346 5336 0 426 400 0 21:35 ? D 0:00 hdparm -i /dev/sdb root 5347 5336 0 463 560 0 21:35 ? S 0:00 grep -q AdvancedPM=yes
These are consistently found every time. Running the hdparm command manually does indeed trigger the error. Stopping acpid fixes the video hiccups. I have a feeling someone more familiar with acpid configuration could figure out the 'proper' fix so it doesn't requery hdparm so often. Moving to the acpid package. -- reading data from firewire drive stalls, ieee1394 errors appear in messages https://bugs.launchpad.net/bugs/440338 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
