hallo,

   I'm developing a hardware application based on theEZ-USB SX2 Chip
from Cypress using libusb-1.0.8 and I see kernel crashes like:

Is it possible for you to reproduce this using a 3.3.y or 3.4-rc
kernel?

And for you to try this on a machine without a closed source kernel
module, and a valid BIOS?


Sorry I was horrible unclear. The original Error line came from an 2.6.38+ kernel, but we see the same error on 3.3.4. The Poison
messages are form an untained 3.3.4 kernel.

What do you mean with valid BIOS ? Anything you see in the debug messages ?

thanks

O.


Gotta love that BIOS string :)

thanks,
