This is a very good description of the problem I have too on my HP
dv9000 laptop.
uname -a:
Linux hp-pc 2.6.22-14-generic #1 SMP Sun Oct 14 21:45:15 GMT 2007 x86_64
GNU/Linux
I boot this kernel with the noapic irqpoll options.
I can get you a full dmesg copy if you really need it, but as far as I can say,
the only relevant part in the log looks like:
[19145.388805] hda: drive not ready for command
[19145.388837] hda: status error: status=0x59 { DriveReady SeekComplete
DataRequest Error }
[19145.388842] hda: status error: error=0x40 { LastFailedSense=0x04 }
[19145.388845] ide: failed opcode was: unknown
and is repeated over and over again.
The dmesg flooding usually starts after a message pops up on my screen
saying a new medium was detected (even though I am not using the DVD
drive in any manner). This seems completely unpredictable. hdparm -w
successfully stops the error message list. Unmounting (right click /
unmount from the desktop) the ghost medium does nothing. The system is
still normally responsive when the bug occurs.
Relevant output of smartctl -a /dev/hda
Device Model: MATSHITADVD-RAM UJ-850S

Before you suggest, I could not find any firmware update for this drive.
If there is one, please let me know!
Also let me know if you need any more information.
