Subject: /usr/sbin/hald: hald confuses HP R707 camera in USB-Storage mode
Message-ID: <email address hidden>
X-Mailer: reportbug 3.38ubuntu2
Date: Fri, 04 Jan 2008 17:15:33 -0800

Package: hal
Version: 0.5.9.1-6ubuntu5
Severity: normal
File: /usr/sbin/hald

hald was crashing the HP R707 camera that was set in "USB Storage" mode.
Stopping hald (/etc/init.d/hal stop) allowed me to
        dd if=/dev/sdb1 of=tmpfile

the entire 256MB SD card. (I initially tried with 32MB SD card in the
camera as output below will show).

If I connect the device while hald is running, I get the follow dmesg
output. Eveything is good up to "Attached scsi generic sg1 type 0"
output. "reset" is because hald is doing something and results in the
deivce going "offline". As noted above, stopping hald allows me to read
from the device.

I don't know which command hald is sending that is causing the
problems but I expect with strace I can figure out which one
takes a long time to complete and fails.

I had stopped udev and this had the original /dev/sdb1 present.
I restarted udev and reconnected the camera:

and /dev/sdb* shows:

and I conclude udev is working correctly.

Since I've upgraded several times, it's probably not a really clean
install...but I don't expect that's the problem in this case.

Please let me know what other information is needed.

Sorry - this is wrong. Somehow I messed up when trying to triag this bug.
udev by itself (without hald) causes the "device offline" issues.
I tried to reproduce this with udev running and discovered it was
happening anyway. So I can't explain how I reached the conclusion
that it was hald. Perhaps there are other problems with hald as well
that caused the same sometimes or interactions with udev or the
same kernel code invoked by udev.

Issues with booting newer kernels on my laptop have made it difficult
to track down exactly which command sent to the device is causing problems.
Once I track that down, we can decide if this bug should be re-assigned
to udev package or whatever is appropriate. It will probably take another
week since I very little time outside of work to track this down.

again, my apologies for the (likely) misdiagnosis,
grant

Basically black list this device since I've demonstrated it's reporting one sector more than it actually has available and then wedges when reading that last, non-existant sector.

Hi Grant,

Sorry for the delayed response. Thanks so much for all the hard work debugging. The patch you attached has already been pulled in to the Hardy kernel. I'll including the Ubuntu Hardy git kernel commit id below for your reference. I'll go ahead and mark this bug as resolved. Thanks again and please continue to report any future bugs that you may find. Thanks!

    Camera will wedge when /lib/udev/vol_id attempts to access the last sector,
