Good work on the c4/hc4. I reloaded my hc4 this week and notice I see IRQ errors (irq37). Under the new Kernel
- there is a hang/slowdown for couple minutes then recovers (from ~37sec to 214sec in this sample)
Just wanted to pass this along and I think a fix might be to add irqpoll to extraargs in uEnv.txt (I usually add the fsck options too as the power sometimes blinks.)
Seems a ok under 4.9.295 so it does not seem to be hardware related.
- reproducible for me under 5.15.12 (and IRQ 37 is Ethernet 10/100/1000) if that is helpful...
less important but also noticeable, under the newer kernel (init 6; reboot; shutdown -r 1) all yield power down without restarting,
- I spun up (slarm64-current-aarch64-base-odroid_c4-5.10.5-build-20210107.img.zst)
-sata is recognized (hc4 model) ((seems to not see sata natively on 4.9.295))
-reboot works

Reason: -
Kernel slowdown / hangs seem fixed, but dmesg still complaining about IRQ#37 on the "hc4"
SATA - working well
- reboot seems to need physical unplug/replug
(which is to say:
init 6
reboot
shutdown -r 1
all leave the hc4 in a frozen (but seemly stopped) state that needs a unplug/replug.
here is a similar problem, but the interrupt is different.
Thanks for that. I rebuilt 5.16.2 from your source package with that patch and I no longer see the IRQ issue and the machine runs nicely. Can you add that to your list of patches for building the next kernels?
Also, I updated the mirrors.aptalaska.net to have the slarm64-15.0 build. It's what I can do to help.

I spoke too soon. The patch causes the kernel to run well and not disable the IRQ, but it no longer allows me to reboot the machine without power cycle.
Disabling the IRQ is less of a problem for me than not being able to remotely reboot.
