Package: linux-image-6.1.0-9-armmp 6.1.27-1

I recently upgraded a Turris Omnia devce
(https://docs.turris.cz/hw/omnia/omnia/) to debian bookworm.  The newer
kernel now produces a pair of repeated error messages a few times a
minute:

Jul 03 05:48:02 host kernel: i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0
Jul 03 05:48:02  kernel: pca953x 8-0071: failed reading register
Jul 03 05:48:19 host kernel: i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0
Jul 03 05:48:19 host kernel: pca953x 8-0071: failed reading register
Jul 03 05:48:57 host kernel: i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0
Jul 03 05:48:57 host kernel: pca953x 8-0071: failed reading register
Jul 03 05:49:25 host kernel: i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0
Jul 03 05:49:25 host kernel: pca953x 8-0071: failed reading register

This appears to be a regression, because the earlier kernel (5.10.0) did
not produce these error messages.

If there is any additional debugging information you'd find useful, i'm
happy to try to gather it.

These log messages are annoying because they mean additional writes to
the logfiles.

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
