I've tried passing the irqpoll option to the kernel boot line, the
sata_via
boot warning disappears but the crashes are still present.
Can it be workaround? Like e.g. making it go at PIO mode 0 i don't need
huge speeds here.
Any idea of what can be causing this? Is it a problem of the
motherboard? Of the adapter? Of the software?
