zfs discuss - Oct 2007 - Areca 1100 SATA Raid Controller in JBOD mode Hangs on zfs root creation.

Just as I create a ZFS pool and copy the root partition to it.... the
performance seems to be really good then suddenly the system hangs all my
sesssions and displays on the console:

Oct 10 00:23:28 sunrise arcmsr: WARNING: arcmsr0: dma map got ''no
resources''
Oct 10 00:23:28 sunrise arcmsr: WARNING: arcmsr0: dma allocate fail 
Oct 10 00:23:28 sunrise arcmsr: WARNING: arcmsr0: dma allocate fail free scsi

AR1100 was running in JBOD mode and write-back caching under Solaris Express Xen
Drop b66 07/07. Never had problem this setup under linux under heavy load.

ARECA SATA-SAS RAID Host Adapter Driver(i386) 1.20.00.13,REV=2006.08.14

I filed a support ticket with Areca with areca already.

Anyone you explain me what the error message is  about? 

Would turning off write-back help? I am going to try that.

Here is the log of what I did to setup the controller using the areca cli:
