>Description:
Hello,

I am trying to use an external scsi raid with an lsi 1020 scsi adapter.

with linux all works well. netbsd (current-6.99.47) reports:

mpt1: mpt_done: IOC overrun!
probe(mpt1:0:0:0): generic HBA error

dmesg only reports:

mpt1 at pci11 dev 8 function 0: vendor 0x1000 product 0x0030 (rev. 0xc1)
mpt1: interrupting at ioapic0 pin 18
scsibus2 at mpt1: 16 targets, 8 luns per target
mpt1: mpt_done: IOC overrun!
probe(mpt1:0:0:0): generic HBA error

I compiled the kernel with SCSIDEBUG,SCSIVERBOSE and SCSIPI_DEBUG.
Unfortunately scsictl still provides no further information.

With Linux (Knoppix) the system works well. Linux detects the hardware as
