USB Bus crash?

[guisacouto]

When I'm downloading a torrent, after sometime, the external hard driver just stops responding, and the wifi dongle also stops working. If I disconnect and connect the hard drive its detected fine. Transmission also crashes when this happens but I guess thats due to the fact that the hard drive is not responding any more and it timeout or something.

here is the dmesg: http://pastebin.com/Y4mnP709

Sorry, that was not very helpful.... There is a kernel bug at the end of mm/alignment.c that needs fixing:

 /* ARMv6K and ARMv7 use fault status 3 (0b00011) as Access Flag section
 * fault, not as alignment error.
 *
 * TODO: handle ARMv6K properly. Runtime check for 'K' extension is
 * needed.*/

if (cpu_architecture() <= CPU_ARCH_ARMv6) {
hook_fault_code(3, do_alignment, SIGBUS, BUS_ADRALN,
"alignment exception");

But this bug is known right? Do you think it's this what's causing my problem?

Yes and no, a lot of people seem to be getting similar problems.

There is certainly a patch in the Linux Kernel which was only applied to V7 CPUs but should be applied to V6K as well, so there is a bug that could be fixed, but I don`t understand what difference that might make. The more I look at it the more confused I become.

Anything you say here gets emailed to Eben and Dom, so if it is important it will get fixed.

Oh ok! Didn't know about the notifications do Eben and Dom; nice to hear that:)
