lsi 1020/1030 problems

[6bone%6bone.informatik.uni-leipzig.de@localhost]

Hello,

I am trying to use an external scsi raid with an lsi 1020/1030 scsi 
adapter. with linux (knoppix) all works well. netbsd (current-6.99.47) 
reports:

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

some output from dmesg:

mpt0 at pci4 dev 8 function 0: vendor 0x1000 product 0x0030 (rev. 0xc1)
mpt0: interrupting at ioapic0 pin 16
scsibus0 at mpt0: 16 targets, 8 luns per target
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


Any Ideas what could be the problem?


Thank you for your efforts
