 to Constantly Reset

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:

> 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

Thanks.
