+++ This bug was initially created as a clone of Bug #456078 +++ Description of problem: Some TEAC drives take a long time to return to non-Busy status following an IDENTIFY command (>=6ms), causing following messages to be logged: 08:20:36 hex kernel: hda: irq timeout: status=0xd0 { Busy } 08:20:36 hex kernel: hda: irq timeout: error=0x00 08:20:36 hex kernel: hda: ATAPI reset complete 08:20:36 hex kernel: VFS: busy inodes on changed media Version-Release number of selected component (if applicable): How reproducible: Infrequently but depends on drive/usage. Some users report the drives to be unusable while others see only infrequent failures. Steps to Reproduce: 1. cat /proc/ide/<drive>/identify Actual results: 22 failures in 60,000 accesses: kernel: hda: task_in_intr: status=0xd0 { Busy } kernel: hda: task_in_intr: error=0xd0LastFailedSense 0x0d Expected results: No error logged. Drive usable as normal. Additional info: Reported upstream as kernel bug 10887: http://bugzilla.kernel.org/show_bug.cgi?id=10887 And fixed in commit f54feafa6d47d0aa1a96adefdc763b708b02f94f: Author: Bartlomiej Zolnierkiewicz <bzolnier> Date: Fri Jun 20 20:53:33 2008 +0200 ide: increase timeout in wait_drive_not_busy() Some ATAPI devices take longer than the current max timeout value to become ready (i.e. TEAC DV-W28ECW takes 6 ms) so increase the timeout value to 10 ms. This fixes kernel.org bugzilla bug #10887: http://bugzilla.kernel.org/show_bug.cgi?id=10887 Reported-by: Masanari Iida <standby24x7> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier> --- Additional comment from bmr on 2008-07-21 08:37:20 EDT --- Created an attachment (id=312253) Patch increasing timeout in wait_drive_not_busy --- Additional comment from bmr on 2008-07-21 08:37:59 EDT --- This is also anecdotaly affecting drives from other vendors. --- Additional comment from bmr on 2008-07-21 08:38:49 EDT --- Related to bug 453808 for the same drive model: qc timeout probing TEAC DV-28E-V CD/DVD drive on SATA/PATA bridge --- Additional comment from alan on 2008-07-23 15:44:40 EDT --- I'm happy with that proposed patch
