6.1 prerelease graid3 livelock?

[Bradley W. Dutton]

Well I don't know what was going on earlier but I reverted to good kernel,
synced my raid arrays (no longer degraded from the panics), then booted a
kernel with the second patch applied, this time no problems so far. I'll
let you know how things go after the box is running for a while.

Thanks,
Brad
