Are there issues with the SiI 3112 chipset and SmartOS? I have a Supermicro machine (SYS-120C-TR) that has been kinda flaky about disks, and I'm pretty sure that not ALL the drives it's gotten unhappy about are bad. Exploring possibilities.

The current problem is generating sequences of these, then marking the drive out for too many errors:

2024-10-24T00:08:41.277383+00:00 copacabana ahci: [ID 777486 kern.warning] WARNING: ahci1: ahci port 3 has interface fatal error

2024-10-24T00:08:41.368466+00:00 copacabana ahci: [ID 657156 kern.warning] WARNING: ahci1: error recovery for port 3 succeed

not that i'm aware of -- i mean.. if it's ahci, it's the same ahci driver used pretty much elsewhere...

unless it's wanting something special others don't...

though i do see in freebsd a reference about what appears to be some DMA bugs in early 3112 chips

How would I examine the version of the 3112 in this system?

you could try prtconf -vd | grep AHCI

or pipe it through less and search for it, then scroll down under the entry and look for the revision id

.... or

Hmm, that's telling me this is integrated in the intel C620 chipset.

/usr/lib/pci/pcieadm show-devs | grep ahci1

that might be a bit easier

or can confirm the above

revision id 00...0a

0/17/0 PCI ahci1 C620 Series Chipset Family SATA Controller [AHCI mode]

ok.. so that's what's generating the errors

so the 3112 is probably not relevant

are the errors always the same port?

No

Although port 3 seems to be the worst

and it's the current round

i'm not aware of any issues with that chip...

maybe check power or cabling

I mean, it could be all sorts of things, headers, cables, drive backplane, yadda yadda

Just figured I'd explore chipset issues.

Thanks for your help!
