Ok, i downloaded the patch before this but i didn't have time yet to
test it.

Ok i've come to the following conclusion. using the config file i've
always used before ncr53c8xx 3.1a gets timeouts
I've tried 2.1.125 with the patch aplied and the old config file which
has the following

CONFIG_SCSI_NCR53C8XX_DEFAULT_TAGS=8
CONFIG_SCSI_NCR53C8XX_MAX_TAGS=4

and with the default which has

CONFIG_SCSI_NCR53C8XX_DEFAULT_TAGS=8
CONFIG_SCSI_NCR53C8XX_MAX_TAGS=32

anyway the timeouts are gone now so i guess the code wasn't the problem
:)
