Are you using irqbalance? Running that would always make my R7800 randomly reboot.

I've been running irqbalance on my nbg6817 (very similar to the the r7800) for about 2 years now (updating to current master builds every couple of weeks), without any unexpected reboots and uptimes in the weeks/ month between sysupgrades.
