I've noticed an odd occurance with the 2.4.15 and 2.4.16 kernels during
testing.
There seems to be a problem with khub.c or it could be my hardware but
I keep getting the following oops and ptrace about 50% of the time
during boot. The following snip is from the boot log of the 2.4.16
kernel compliled this afternoon.
If anyone has any ideas or a suggested fix.

Does this happen when you plug in your device after Linux is booted?
Can you send the output of /proc/bus/usb/devices with the device plugged
in (if it doesn't always cause an oops)?
Can you run that oops through ksymoops and post it?
thanks,

Greg,
The oops only occurs at startup. here's the oops parsed through ksymoops
