Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

After thinking about what I changed lately besides distribution package updates it came to my mind that I upgraded from kernel 6.4.x to 6.5.x lately (kernels and their upgrades are manual on my distribution so no package was used). I used an arch linux iso to boot my system which also used a previous kernel and worked fine, compiled a 6.4.x kernel again on the system, specifically the latest 6.4.16 one. Rebootet and everything is up and running fine again so after half a day I'm pretty sure none of my hardware is faulty and it's indeed a kernel issue/regression.

See Bugzilla for the full thread.

Anyway, I'm adding this regression to be tracked by regzbot:

#regzbot introduced: v6.4..v6.5 https://bugzilla.kernel.org/show_bug.cgi?id=217920
#regzbot title: UDMA configured spam on Marvell RAID controller

Thanks.
