Hi,
I notice a regression report on Bugzilla [1]. Quoting from it:
After upgrading to 6.5.2 from 6.4.12 I keep getting the following kernel messages around three times per second:
[ 9683.269830] ata16: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[ 9683.270399] ata16.00: configured for UDMA/66
So I've tracked the offending device:
ll /sys/class/ata_port/ata16
lrwxrwxrwx 1 root root 0 Sep 10 21:51 /sys/class/ata_port/ata16 -> ../../devices/pci0000:00/0000:00:1c.7/0000:0a:00.0/ata16/ata_port/ata16

0a:00.0 SATA controller: Marvell Technology Group Ltd. 88SE9128 PCIe SATA 6 Gb/s RAID controller with HyperDuo (rev 11)
I am not using the 88SE9128, so I have no way of knowing whether it works or not. It may simply be getting reset a couple of times per second or it may not function at all.
See Bugzilla for the full thread.
patenteng: I have asked you to bisect this regression. Any conclusion?
Anyway, I'm adding this regression to regzbot:
#regzbot: introduced: v6.4..v6.5 https://bugzilla.kernel.org/show_bug.cgi?id=217902
Hello Bagas, patenteng,
FYI, the prints:
[ 9683.269830] ata16: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[ 9683.270399] ata16.00: configured for UDMA/66
Just show that ATA error handler has been invoked.
There was no reset performed.
If there was a reset, you would have seen something like:
[ 1.441326] ata8: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
[ 1.541250] ata8.00: configured for UDMA/133
[ 1.541411] ata8: hard resetting link
Could you please try this patch and see if it improves things for you:
https://lore.kernel.org/linux-ide/20230913150443.1200790-1-nks@xxxxxxxxxxx/T/#u
FWIW, I'm seeing a very similar issue both in 6.5.2 and in git master
[aed8aee11130 ("Merge tag 'pmdomain-v6.6-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/linux-pm") with that
patch applied.
The log is similar (the last two lines repeat several times a second):

Kernel driver in use: ahci
The controller in question lives on a Gigabyte Z87X-UD5H-CF motherboard.
I'm using the controller for several drives, and it's working, it's just
spammy. (At worst, there's some performance hitching, but that might
just be journald rotating logs as they fill up with the message).
I haven't had a chance to bisect yet (this is a slightly awkward machine
for me to install test kernels on), but can also confirm it worked with
6.4.12.
Hopefully that's useful. I'll get back to you if I manage to bisect it.
Cheers,
