FreeBSD 6.0 has problems with Symbios/LSI-HBAs

[Juergen Dankoweit]

Hello to the list.

On my production server (private and at firm) I had the possiblity to
test the new FreeBSD 6.0 RC1 and REALESE in the downtime.

Both systems are Siemens Primergy 470, dual PIII 450 MHz, two LSI 83C895
SCSI-HBAs (one onboard and one on a separate PCI card).
At the onboard HBA all HDDs are LVD drives.
At the second only single ended devices are connected.
The termination is correct.

On both systems it is imposisible to install FreeBSD 6 because it hangs
at this position:

(noperiph:sym0:0:-1:-1): SCSI BUS reset delivered.
(noperiph:sym1:0:-1:-1): SCSI BUS reset delivered.
(noperiph:sym1:0:-1:-1): SCSI BUS mode change from SE to SE.

here stops the system.
After about five minutes the following messages are shown character for
character.
(When the SAF/TE is connected)
(probe7:sym0:0:8:0): phase change 6-7 6 at 0f76058c resid=4.
ses0 at sym0 bus 0 target 8 lun 0
ses0: <SIEMENS STM/L S1 4.1b> Fixed Processor SCSI-2 device
ses0: 3.300MB/s transfers
ses0: SAF-TE Compliant Device

(When the SAF/TE is NOT connected it jumps directly to these messages)
da0 at sym0 bus 0 target 0 lun 0
da0: <COMPAQ BD036735C8 B020> Fixed Direct Access SCSI-2 device
da0: 80.000MB/s transfers (40.000MHz, offset 31, 16bit), Tagged Queueing
Enabled
da0: 34732MB (71132000 512 byte sectors: 255H 63S/T 4427C)

And here nothing goes on. 

Exactly this behavior was on FreeBSD 5.3 STABLE-1. It was fixed with
FBSD 5.3 STABLE-2. FreeBSD 5.4 runs also perfect on these machines.
But in the new version of FreeBSD the same bug comes again. 

On the production machines it is impossible to install or upgrade the
new FreeBSD 6 to do more tests.

Please send an email if more information is needed, but let me say
again: these machines are production servers. I don't have the
possibility to compile any kernels or change adapters.

Many thanks for your help.

Best regards
