Unhandled IRQ at boot or when unloading mt7630e

[euspectre]

The issue https://github.com/kuba-moo/mt7630e/issues/19 seems to affect this variant of the driver as well.

Sometimes the following error is reported to the system log at boot time or when I try to unload mt7630e:

irq 16: nobody cared (try booting with the "irqpoll" option)

Disabling IRQ #16

When it happens at boot, the system hangs and becomes unusable until reboot (even no reaction to the magic sysrq).

If I blacklist the driver at boot (modprobe.blacklist=mt7630e), the problem have not shown up so far.

OS: ROSA Linux R6 x86_64 Kernel: 4.1.15 WiFi adapter: pci:14c3-7630-103c-197c (MT7630e 802.11bgn Wireless Network Adapter)

More details and the logs: http://hw.rosalinux.ru/index.php?probe=050ffb018c I had to reboot the system before collecting them, so the full system log of the previous problematic boot is http://hw.rosalinux.ru/index.php?probe=050ffb018c&log=journalctl.1

Any ideas?
