Comment 231 for bug 1220146

with tobiasbora solution i also get 100% cpu on ksoftirqd
I am not sure if it helps but trying acpi=off the module does not load and I get a multitude of the messages

===>rt2x00lib_start
genirq: Flags mismatch irq 0. 00000080 (0000:03:00.0) vs. 00015a00 (timer)
phy0 -> rt2x00lib_start: Error - IRQ 0 allocation failed (error -16).

As an aside, would it help if more people contact mediatek? I sent a question on their webform but haven't received a reply.
