Now I have also replaced the PSU with a much better specced unit, so that may have also been a contributing factor to the oops. (The 12v rail was running on the edge).
If this rebuild this morning gets through then I'll go back to the old kernel that was oopsing and try it again to compare.
Ok, I have beat on all the kernels I have available. 2.6.10-bk10, 2.6.11-rc4-something, 2.6.11-rc4-bk6 and 2.6.11-bk8 all with the libata-dev patches of the time, and none of them oops now. It *must* have been a flaky PSU.
SMART polling does cause the occasional drive timeout, causing the drive to be booted from the array, but nothing fatal and I have to be seriously hammering the disks with both I/O and SMART requests to get it to occur.
Sorry for the noise.
