FYI: Souce files of the Dawicontrol DC 2976 UW SCSI board (PCI):
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/scsi/sym53c8xx_2?h=v5.4-rc7

/*
 *  DMA addressing mode.
 *
 *  0 : 32 bit addressing for all chips.
 *  1 : 40 bit addressing when supported by chip.
 *  2 : 64 bit addressing when supported by chip,
 *      limited to 16 segments of 4 GB -> 64 GB max.
 */
#define   SYM_CONF_DMA_ADDRESSING_MODE
CONFIG_SCSI_SYM53C8XX_DMA_ADDRESSING_MODE

Cyrus config:

CONFIG_SCSI_SYM53C8XX_DMA_ADDRESSING_MODE=1

I will configure “0 : 32 bit addressing for all chips” for the RC8. Maybe this
is the solution.
