[2.6.30-rc2] CD-R: wodim intermittent failures: [sr0] Add. Sense: Logical block address out of range, sector 0

[Andy Isaacson]

I'm running 2.6.30-rc2-00446-ga939b96 on a Dell E4300 with a
upgraded-to-Jaunty-mostly Ubuntu install.  Using 2.6.28 and 2.6.29.1,
I've successfully burned a dozen CDRs, but since updating to .30-rc1
I've noticed intermittent failures to burn CDRs using wodim at the Gnome
desktop.  (Switching back to .29.1 makes wodim reliable again.)  There
have been a few different failure modes, but all of them seem to be
associated with these messages in dmesg, which I haven't seen before:

[  360.740810] sr 1:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
[  360.740816] sr 1:0:0:0: [sr0] Sense Key : Illegal Request [current] 
[  360.740820] sr 1:0:0:0: [sr0] Add. Sense: Logical block address out of range
[  360.740826] end_request: I/O error, dev sr0, sector 0
[  360.740830] Buffer I/O error on device sr0, logical block 0

(repeated a few dozen times).

I haven't been able to reproduce these messages running wodim at the
console (after "/etc/init.d/gdm stop") so I suspect there's some
interference between wodim and Gnome's desktop device detection.

I've seen the following behavior running wodim under gnome:

1. wodim blocked in D state for >10 minutes, system showing interactive
lagginess.  Unfortunately I've not been able to reproduce this to get
wchan info, but I *think* it was showing blk_execute_rq.

2. running wodim triggers DID_OK messages, but wodim seems to be able to
complete writing the ISO and the resulting CDR reads OK.

3. running wodim triggers DID_OK messages, and wodim fails:  (but I
think this is just due to the media having been partially written by a
previous iteration of wodim.)

I'm running "wodim ubuntu-9.04-rc-desktop-amd64.iso" as a regular user
with group write permissions to /dev/sr0.

I've seen /lib/udev/vol_id running *after* wodim has opened the device,
so I wonder if there's some race condition there.

This is with udev 140-2 and wodim 9:1.1.9-1ubuntu1.  .config and
