Hi,
I'm seeing a problem using dm-verity with the sha256-dcp driver
(mxs-dcp). Specifically, I'm seeing corruption errors a la
device-mapper: verity: 179:2: metadata block 76823 is corrupted
This is a regression that has started to appear with commit
c25da5b7baf1d dm verity: stop using WQ_UNBOUND for verify_wq
Reverting that commit while keeping an identical rootfs fixes my issue
and I don't get any warnings anymore. I'm using an i.MX6ULL SoC which
only has one CPU core so I don't really understand how WQ_UNBOUND can
have an affect here. However, there might be side effects that I'm not
aware of.
It might be worth noting that I'm using the dm-verity device as my root
device without initramfs. I'm seeing this on both v6.6.23 and today's
master (v6.10-rc1-13-g2bfcfd584ff5c).
Does anyone have ideas, how WQ_UNBOUND could be required here?
Thanks,
Sven
