Summary: The ibmcam driver is not working
Product: Drivers
Version: 2.5
Kernel Version: 2.6.34
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: USB
AssignedTo: greg@xxxxxxxxx
ReportedBy: davidsen@xxxxxxx
Regression: Yes
This driver has been working, and around the 1st of May I updated my Fedora
kernel (FC13-RC) to current. The camera stopped working, so I built the latest
2.6.34-rc version and verified the problem. When 2.6.34 final released I
repeated the test and the driver is still not working.
Originally reported against Fedora (not going to be fixed in FC13) the
information in the Fedora report may be enough to identify the problem. I can
do a bit of test almost any day, but the cams are on a video monitoring system,
so I'm not able to do long bisects and such.
It's a 2.6.33 -> 2.6.34 regression, I think. I don't know whether it's
a v4l problem or a USB one..
I noted this problem in Fedora kernels:
2.6.33.2-41.fc13.x86_64 - worked
2.6.33.2-57.fc13.x86_64 - fails
The first was on my video server 4/21 when I left for a trip to the midwest,
and worked perfectly with the "motion" app for the entire ten days. When I
installed the current update on 5/2 or so it stopped working. I did go back
and boot the older kernel and it still works, not some bizarre hardware thing.
After boot I have /dev/video0 as the ibmcam, but after first attempted use
the device is gone. Since it worked in older kernels I rebooted and tried
running it in an older VM (fc9) using USB passthru to KVM. That also didn't
work. Does that tell anyone more than it tells me?
