Default Bug#679519: same on non-RT kernel ( usbhid causes crashes in applications by memory corruption)

Is that a standard (non-realtime) kernel? If not, can you also test a
standard kernel configuration (linux-image-3.2.0-3-amd64)?


Identical behaviour on linux-image-3.2.0-3-amd64


Please try booting with the extra kernel parameters:

memory_corruption_check=1 memory_corruption_check_size=640K memory_corruption_check_period=5

Does that avoid the problem, and if so what does the kernel log show
after you plug in the device?


It seems that X86_CHECK_BIOS_CORRUPTION is disabled in the Debian kernels. I'm compiling a custom
one with it enabled and will post any significant results.

Oops, sorry, I thought we had it enabled.
