I also see "PCI DMA Bus Error" on the FreeBSD side :

isp0: isp_action code 933
(targ0:isp0:0:0:0): isp_target_start_ctio: CTIO2[1d7c] flags 40 xfrlen 4 
offset 0
isp0: RISC2HOST ISR 0x2718013
isp0: PCI DMA Bus Error
isp0: data CTIO complete
isp0: isp_handle_platform_ctio: CTIO2[1d7c] sts 0x10 flg 0x840 sns 0 
resid 0 MID
isp0: MIDTERM  CTIO[0x1d7c] done

This seems to follow the "Firmware timed out" error.

Thanks,
Leo.
