Description Manuel 2011-01-12 11:37:45 UTC 
hello,

since i am using 2.6.37 there is a problem with the em28xx driver.
seems to be a bug in the new kernel, cause there wasn't a problem with kernels up to 2.6.36.

the error appears on unplugging the usb device or just on rmmod the em28xx driver.

the stack trace is attached.

if i try to reload the em28xx driver after this failure, the system is freezing.

(big kernel lock is actually off in my kernel, but setting it on again doesn't fix the problem!)
