PROBLEM: cp210x

Dear Sir or Madam,

I would like to report a bug sice kernel 3.3.1.

[1.] One line summary of the problem:

	The module cp210x causes kernelpanic.

[2.] Full description of the problem/report:

By connecting a usb-device with ID 10c4:ea60 to the computer the module
cp210x causes a recursive fault and the kernel is halted.

[3.] Keywords (i.e., modules, networking, kernel):

	module: cp210x, usb to serial converter, kernel 3.3.1, kernel 3.3.2,

kernel 3.3.3

[4.] Kernel version (from /proc/version):

	Linux version 3.3.3-1-ARCH (tobias@T-POWA-LX) (gcc version 4.7.0

20120414 (prerelease) (GCC) ) #1 SMP PREEMPT Mon Apr 23 09:41:07 CEST 2012

[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)

it was not possible to save the oops message. but at the and there was
a line with "recursive fault fixed, but system has to reboot"

[6.] A small shell script or example program which triggers the
problem (if possible)

[7.] Environment
[7.1.] Software (add the output of the ver_linux script here)

Thank you

Leaving in the whole message for linux-usb.

Can you make a readable photo of the screen with a digital camera and post it somewhere?

Or, connect the box to a serial or a firewire console?

If the oops is still whizzing by too fast, try enabling CONFIG_BOOT_PRINTK_DELAY, see the help text with this option in the configurator too, for more info.

Regards/Gruss,
Boris.
