Bug#679519: unable to obtain better info (Re: usbhid causes crashes in applications by memory corruption))



After building a kernel with X86_CHECK_BIOS_CORRUPTION enabled, I set it to scan (almost) as advised. No corruption of the low memory was reported after running some hours either with or without usbhid loaded.

(Booting with memory_corruption_check_size=640K caused an immediate kernel panic -- early exception 08 --though. Changing it to 620k allowed the boot to continue normally.)

I took the opportunity to include kmemleak in the new kernel as well. After some uptime, one orphan object was always found, but it happened either with or without usbhid ever having been loaded. To judge from the traceback it was something ACPI-related anyway.

So, basically, no progress.
