Hi,
I'm been having a strange problem with various builds of FreeBSD - 5.2-RELEASE
(at least) and up to 5.3-BETA4. Random hard lockups are occuring when writing
to two separate SATA drives. Sometimes the lockups occur under high IO, but not
always. Due to the random nature of the lockups, I don't have much hard evidence
and information to provide. How can I go about gathering more information? I've
tried enabling WITNESS and other kernel debugging options, but no extra
debugging data was produced.
The drives aren't configured as RAID -- they are accessed separately and not
configured in any special way. They are two 160G Seagate SATA (ST3160023AS)
drives that are being accessed via their ar* devices. I've also tried accessing
them directly via their ad* devices, but the lockups still occured.
smartmontools report the drives as good on both long and short tests.
Any suggestions would be appreciated.
Thanks!
