sata_nv issues with MCP51 SATA controller
|
|
Hi, I'm resending (didn't see my first attempt appear on the maillist):
I'm having serious disk-issues when using the on-board nvidia controller
for my HDDs (My motherboard is a Gigabyte GA-N650SLI-DS4 with nvidia
chipset, cpu is intel Core2Quad)
excerpt from "lspci":
00:0d.0 IDE interface: nVidia Corporation MCP51 IDE (rev a1)
00:0e.0 IDE interface: nVidia Corporation MCP51 Serial ATA Controller
(rev a1)
00:0f.0 IDE interface: nVidia Corporation MCP51 Serial ATA Controller
(rev a1)
I have a normal IDE/P-ATA-disk attached to the "IDE"-controller and that
works fine (/dev/hda)
However, any number of disks (I have tried 2 and 4) connected to the
SATA-controller(s), will eventually fail. - See attached log (excerpt /
anything relevant from /var/log/messages)
At first, disks were REALLY unstable, but then I disabled S.M.A.R.T.
(both in BIOS and Linux), and I updated from the CentOS5 (equivalent of
RHEL5) kernel (2.6.18) to the latest (at that time) official kernel from
kernel.org:
> uname -a
Linux mirakel 2.6.22.5-custom_jir #2 SMP Thu Aug 30 22:06:21 CEST 2007
i686 i686 i386 GNU/Linux
Now it will normally take a day or two before SATA crashes, so things
are better, but still rather useless.
First error when sata_nv get into problems is always:
"exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen"
(as shown in the attached log-file.) - when this happens to one device,
it'll almost instantly happen to the other disk attached to that
controller as well. A couple of minutes (or so) later, the disk(s)
connected to the other controller will start acting up as well (in the
same manner). - I/O freezes, and nothing helps except a reboot...
As I run a rather large (software / md) RAID-5 disk array on this server
(I'm doing a bit of video editing), every crash means a time-consuming
rebuild of the disk-array...
I have given up on the sata_nv / nvidia-controllers for the time being.
I now resort to some old PCI-connected sata-controllers which work fine
(but slow, as they are outdated and "overloaded").
So, if anyone has a good solution / suggestion / improved driver (over
the one supplied with the official 2.6.22.5-kernel) I am eager to give
it a go and see if the situation can be resolved.
I appreciate any sensible suggestions.
