I've spent a lot of time on this.
At some point I started suspecting
disk failures, based on dd errors and smartmontools
reports. So I replaced the disks,
and then replaced the whole box for
another nominally identical SunBlade 1500.
The panics persisted.
I now think that multiple cold reboots
might have damaged disks, not the other
In the end I had to conclude that this
is not a hardware problem, but the OS issue,
perhaps triggered by some heavy disk I/O.
Various frequent panics exist at least from
r260689 to r263096:
I now reverted as far back as r258000, and
the system seems stable, but I probably
need few more days to be sure.
If the system is indeed stable at r258000,
when I have the time, I'll try to narrow
down the problem revision. But I'd appreciate
any hint that might save time.
