Sorry, a few lines of the syslog output were truncated in my copy-paste. Here's the remaining lines which follow those already in the description.

This bug was reported for 2.6.5-1.358smp. I'm now running 2.6.8-1.521smp. This may be fixed? |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040510 Description of problem: A CD drive frequently locks up after being left idle. The eject button does not work. And all commands that attempt to access it will lock up for a long period of time in a "disk sleep" state, until the kernel outputs a bug report to syslog, a few lines of which read: Jun 3 15:34:46 deron kernel: kernel BUG at fs/buffer.c:1214! Jun 3 15:34:46 deron kernel: invalid operand: 0000 [#1] This is bus ide1, which has two devices, a DVD-ROM and a CD-RW. The CD-RW is the one which seems to lock up first, but afterwards both devices are inoperable. This system worked fine under FC1. A soft reboot also clears up the problem. This is a stock FC2 system with SMP kernel. There may be a related buf report on LKML? http://lkml.org/lkml/2004/5/19/191 Additional system details and complete syslog output are in additional info below. Version-Release number of selected component (if applicable): 2.6.5-1.358smp How reproducible: Sometimes Steps to Reproduce: 1. Let system set idle some indeterminate period of time 2. Try ejecting CD tray 3. Actual Results: Tray won't eject. Launching any command which attempts to access the device will lock up. Additional info: Output of syslog during one of these events: ------------CUT------------ Jun 3 15:32:30 deron kernel: hdd: irq timeout: status=0xd0 { Busy } Jun 3 15:32:30 deron kernel: hdd: irq timeout: error=0x00 Jun 3 15:32:30 deron kernel: hdd: DMA disabled Jun 3 15:33:00 deron kernel: hdd: ATAPI reset timed-out, status=0x80 Jun 3 15:33:00 deron kernel: hdc: DMA disabled Jun 3 15:33:30 deron kernel: ide1: reset timed-out, status=0x80 Jun 3 15:33:37 deron kernel: hdd: status timeout: status=0x80 { Busy } Jun 3 15:33:37 deron kernel: hdd: status timeout: error=0x01IllegalLengthIndication Jun 3 15:33:37 deron kernel: hdd: drive not ready for command Jun 3 15:34:07 deron kernel: hdd: ATAPI reset timed-out, status=0x80 Jun 3 15:34:39 deron kernel: ide1: reset timed-out, status=0x80 Jun 3 15:34:44 deron kernel: udf: registering filesystem Jun 3 15:34:46 deron kernel: udf: bad block size (2048) Jun 3 15:34:46 deron kernel: ------------[ cut here ]------------ Jun 3 15:34:46 deron kernel: kernel BUG at fs/buffer.c:1214!
