Hi list,
I seem to have a bug with JMicron controller in a Gigabyte GA-N680SLI-DQ6
motherboard.
http://www.gigabyte.com.tw/Support/Motherboard/BIOS_Model.aspx?ProductID=2460
Kernel is 2.6.24.
10 on-board SATA connectors, 2+4*JMicron 20360/20363 + 4*nVidia MCP55
2*200GB disks (System - SW RAID1) on the JMicron controller and
8*500 (Data - SW RAID6) - 4 on the JMicron, 4 on the nVidia controller.
Under heavy load the JMicron controller gets exceptions, then eventually
"hard resetting link".
All 4 disks/connector, one after another. This of course "kills" the RAID

Didn't dare to post all attachments, so
full dmesg
lspci -nn
syslog - from the error start
can be downloaded from:

I'm lost.
Anyone seen such thing? What could it be? Hardware (MB, chipset, BIOS),
kernel (driver) or what?
Any suggestion? Kernel version to try, dispose hardware or shoot myself in
the head?
Thanks,
Gabor
