Did you test 2.1.107 and 2.1.108 or 109?

Around that, ncr driver version 3.0 was introduced. It is this version
only that caused trubble for me.

Gerard Roudier suggested to use sym53c8xx-0.4 from

ftp://ftp.tux.org/pub/roudier/896/

which now works fine for me with 2.1.107 and 2.1.117.

We also introduced some dummy u_long variables at various places in
driver 3.0g (from kernel 2.1.117). This made the M_REJECT´s go away
but caused some random 1-2second lockups, indicating memory corruption.

Of course, i really tried hard to avoid any violation of scsi standards
before!

Now i´m happily using:

CONFIG_SCSI_NCR53C8XX=y
CONFIG_SCSI_NCR53C8XX_DEFAULT_TAGS=8
CONFIG_SCSI_NCR53C8XX_MAX_TAGS=32
CONFIG_SCSI_NCR53C8XX_SYNC=20
