After resolving problem with kernel stack overflow, I have applied
ata-all.patch. It really solves a problem!
However, problems of a similar nature arise if USB CardBus inserted.
System freeze when resumed and sleep in "usbdly". From sources:
---[sys/dev/usb/usb_subr.c]---------
/* Delay for a certain number of ms */
void
usb_delay_ms(usbd_bus_handle bus, u_int ms)
{
/* Wait at least two clock ticks so we know the time has passed. */
if (bus->use_polling || cold)
delay((ms+1) * 1000);
else
tsleep(&ms, PRIBIO, "usbdly", (ms*hz+999)/1000 + 1);
}
---[sys/dev/usb/usb_subr.c]---------
