Subjectoops in 2.5.63: kernel BUG at drivers/usb/storage/usb.c:972
From
Date
while trying (unsuccessfully) to connect my sony dsc-f717 digital
camera to my sony vayo laptop (pcg-xcg19, piii at 650 MHz) i got the
following oops when i turned off the camera (the memory stick was
recognized as a scsi device, but when i tried to mount it, the mount
command hung):

ksymoops 2.4.8 on i686 2.5.63. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.5.63/ (default)
-m /boot/System.map-2.5.63 (default)

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
