ZFS hangs with 8.2-release

[peter håkanson]

i have seen problems with freebsd 8.2 and 9.0 on sun thumper ( x4500) 
where the bios logs shows "Hyper transport sync flood" will get into the BIOS errorlog ( but nothing will come to syslog since reboot is immediate)

This was discussed on freebsd.freebsd-stable jan 18 2012

There was no solution with freebsd, to my dismay solaris works  well on the same box :-)

Maybe x4200 has simular design issues ( had to do with routing of interrupts
to the available cpu's)
