You have provided no context here :( My apologies -- what I meant to say was: I inserted the compile usbrsa driver. The code of the driver I posted on Feb 16th.

The kernel freezes before it can log the kernel oops: Feb 19 07:26:35 btron kernel: [ 241.247360] usbcore: registered new interface d river usbrsa Feb 19 07:26:35 btron kernel: [ 241.247388] usbserial: USB Serial support regis tered for IO-DATA - USB-RSA - (prerenumeration) Feb 19 07:26:35 btron kernel: [ 241.247412] usbserial: USB Serial support regis tered for IO-DATA - USB-RSA ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@ .... > The kernel logs can provide you with a full traceback, we can't do much > without that. I understand that and I would love to provide one -- there is however no traceback logged. All I have is a kernel message on the console: BUG: unable to handle kernel paging request at ... When I had the driver running on the kernel version 3.13.0, things started to go wrong in usbrsa_attach of the usbrsa driver (see first posting on Feb 16th) I will comment out all functional parts of the driver, and check if it still fails. If it no longer crashes, I will comment in procedure by procedure until it crashes hoping that I can isolate the problem that way ... If there are better/faster debugging techniques I would love to learn about them :-) Thanks Tilman -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
