It seems all these messages result from a single call to flush_dcache_page. Note the sequential behavior of old_addr
and addr, and message times.
FWIW, from Helge's config on 5.10.108 (config changes on my end: just disabling unneeded devices to speed up build), I have the same
horrible wall:
This change might help:
https://lore.kernel.org/linux-parisc/YlNw8jzP9OQRKvlV@mx3210.localdomain/T/#u
It applies on top of Helge's current for-next tree which is based on 5.18.0-rc1+.
The messages will no longer appear with this patch on c8000/rp34xx. However, the loop corruption
might still occur. If that happens, I think the stall detector will trigger, or maybe some other crash.
The loop is changed to flush all mount points on machines with PA8800 or PA8900 processors as I
believe these CPUs don't support equivalent aliases.
