with tags enabled, iSCSI is much faster, but it also causes a deadlock :-(
this is what i run:
newfs -U /<iscsi device>
cd /<iscsi device>
restore rf /home/file.dump
on the same motherboard, a dual Xeon, with smp disabled all is OK
with smp enabled restore gets stuck usualy waiting on biord.
the iscsi driver shows that all requests have been done, the sniffing
shows the same(ie all request have been done).
so this leads me to think that there is some race condition that i'm not
aware of in a SMP system, where xpt_done(ccb) is called while
another process is calling biowait.
another lead is that after restore gets stuck, the system slowly gets
'stalled'.
any insight is most welcome!, i'm also stuck.
