I believe it was 4.5-STABLE around Feb 10 - I sent the following
message on that date:
--
I restarted the bento build with the 4.x package set, after upgrading
the gohans to 4.5-STABLE (one of them had panicked with ffs_alloc: dup
alloc). I also set up the gohans to scrub their disks at boot time.
--
Prior to this, I think they were running 4.4-STABLE as of about Nov
25, which was the last time I upgraded them. I don't think I've seen
a recurrence of the dup alloc panic lately, so this might have been
fixed between November and January.
Combined with the alpha kernels running from around Jan 26 this seems
to narrow the range a fair bit.
Kris
