sym53c875 error

[Hamilton, Eamonn]

Hi Folks.

Under all of the kernels I have access to try ( 2.2.19, 2.4.X & 2.4.X-ac* ),
when I try and write an image in XA2 format to my SCSI writer ( Yamaha
CDR-400t ), I get a DMA overrun. When I try with a kernel patched with the
beta symbios driver ( 2.1.9 ), it works just fine.

This is on a Debian woody system, using cdrecord 1.10 ( also 1.9 and 1.8
with the same symptoms ) attached to a Tekram DC390F.

Transcript as follows :

cdrecord dev=0,3,0 -dummy -xa2 firmware.iso

And while that lot happens, I get

sym53c875-0-<3,*>: target did not report SYNC.
sym53c875-0-<3,*>: extraneous data discarded.
sym53c875-0-<3,*>: COMMAND FAILED (89 0) @c12a3800.

Standard burns work ok, it's just the xa2 stuff I have a problem with so
far. I also tried using the old NCR driver with the same results.

Anybody got any ideas?
