...This output is from the
run with your patch.
I am using libvirt (virt-manager) to configure and run the virtual
machine, but looking at the xml, I do not think it's passing
'scsi=off' at all.
Btw, that xfs file system is a root file system.

using mplayer and a higher debug level, what I *think* the significant
message is (this is just one example line):
libv4lconvert: Error decompressing JPEG: fill_nbits error: need 5 more bits
fps = 15.626953, interval = 0.096001, a_skew = 0.000000, corr_skew = 0.000000
vcnt = 1, acnt = 0
Which seems to indicate that for some reason, on *some* hardware,
libv4lconvert is doing something wrong that it did correctly in the last

Is anyone using an older USB webcam that can look at this issue? I can't
really test it on our RHEL box (well, I suppose I could try...
