00:23:24 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. 00:27:59 The current problem is generating sequences of these, then marking the drive out for too many errors: 00:28:02 2024-10-24T00:08:41.277383+00:00 copacabana ahci: [ID 777486 kern.warning] WARNING: ahci1: ahci port 3 has interface fatal error 00:28:05 2024-10-24T00:08:41.277409+00:00 copacabana ahci: [ID 687168 kern.warning] WARNING: ahci1: ahci port 3 is trying to do error recovery 00:28:08 2024-10-24T00:08:41.277419+00:00 copacabana ahci: [ID 551337 kern.warning] WARNING: ahci1: #011Transient Data Integrity Error (T)#012#01110B to 8B Decode Error (B)#012#011CRC Error (C)#012 00:28:12 2024-10-24T00:08:41.368466+00:00 copacabana ahci: [ID 657156 kern.warning] WARNING: ahci1: error recovery for port 3 succeed 00:31:02 not that i'm aware of -- i mean.. if it's ahci, it's the same ahci driver used pretty much elsewhere... 00:31:12 unless it's wanting something special others don't... 00:32:37 though i do see in freebsd a reference about what appears to be some DMA bugs in early 3112 chips 00:36:29 How would I examine the version of the 3112 in this system? 00:38:30 you could try prtconf -vd | grep AHCI 00:41:46 or pipe it through less and search for it, then scroll down under the entry and look for the revision id 00:41:49 .... or 00:42:19 Hmm, that's telling me this is integrated in the intel C620 chipset. 00:42:32 /usr/lib/pci/pcieadm show-devs | grep ahci1 00:43:19 that might be a bit easier 00:43:23 or can confirm the above 00:43:31 revision id 00...0a 00:44:04 0/17/0 PCI ahci1 C620 Series Chipset Family SATA Controller [AHCI mode] 00:44:14 ok.. so that's what's generating the errors 00:44:30 so the 3112 is probably not relevant 00:44:35 are the errors always the same port? 00:44:39 No 00:44:50 Although port 3 seems to be the worst 00:45:51 and it's the current round 00:47:48 i'm not aware of any issues with that chip... 00:48:07 maybe check power or cabling 00:48:41 I mean, it could be all sorts of things, headers, cables, drive backplane, yadda yadda 00:48:57 Just figured I'd explore chipset issues. 00:49:03 Thanks for your help!
