You didn't tell us what kernel version this is.

Comment 3 la_antorcha_guia 2012-02-29 10:05:02 UTC 
I think that HPET (VIA) enabled could cause this. I need more test...
Comment 4 la_antorcha_guia 2012-03-04 20:50:38 UTC 
seems that HPET VIA could cause this problem
Comment 5 Stanislaw Gruszka 2012-03-05 08:42:19 UTC 
Hmm, I planed to provide rt2800usb test patch for that problem, but did not find time to prepare it. 

Could you elaborate more on that bug? Is HPET VIA wrongly measure a time so we see timeouts, whereas only small amount of time elapses ?

I think that problem is in kernel VIA HPET support. HPET enabled generates thousands on problems (disk errors, ethernet loses, usb errors, ...) on 3.X kernels.

Better solution, disable VIA HPET, or, upgrade VIA HPET (bad documented) kernel support, or, do not buy VIA products,...
