...and on that point in particular, it really depends on your hardware.
You shouldn't need to do either of those things just to avoid this bug,
but if your hardware actually supports VI or EIC then it may be
beneficial to enable them.
Checking again, the MT7688 supports VI. config3=00002420, so VInt (Bit 5)
is set. But without CONFIG_CPU_MIPSR2_IRQ_VI being set, cpu_has_vint will
stay set to zero. So it seems that I need set CONFIG_CPU_MIPSR2_IRQ_VI
at least for this SoC (CONFIG_SOC_MT7620) if not even for all Ralink
based SoC's.
If nobody objects, I'll submit a patch enabling CONFIG_CPU_MIPSR2_IRQ_VI
for CONFIG_SOC_MT7620.
Thanks,
Stefan
