Bug#284535: kernel / usb bug
Package: kernel
Version : 2.6.8-1-386
(New install of sarge)
Connected a TwinMOS 7 in 1 card reader which was detected fine. It had a 64Mb
CF card in the first slot.
I mounted it using mount -t vfat /dev/sda /mnt/twinmos_cf
Created a directory and then tried to copy a 22Mb file to it.
Looks like the cards u/s, but "kernel BUG" showed up twice.
dmesg showed the following:
