The system is not overclocked. :- Although I have reported successful use of CAM on a machine with U2W disks couple weeks ago. I have the same problem now. I have Micro-star ATX LX6 Motherboard with Intel 82371AB chipset (Pentium II 266MHz) , PCI Adaptec 2940U2W and Seagate 32272W, 32151N and 2x 39173 LW disks. Even if the only disk left is the 32272W (system disk) I'm getting: "ahc0: brkadrint, Data path Parity Error at seqaddr=0x17e" message during the boot. Sometimes (very rarely) I succeed to boot. The behavior is hard to predict. Originally I thought it had something to do with the SCSI termination, cables too close to the power source unit etc. because it usually stopped working after I put the cover on the machine, put it from the table on the floor etc. The discussion 19980716 versus 980520 snapshot made me to try one experiment. When the 980520 snapshot was released Adrzej Bialecki (hopefully I remember the spelling correctly) announced a boot.flp with 980520 CAM snapshot. Now I downloaded the boot.flp from the 19980716 distribution and tried to boot from both. The 980520 booted without problem but the 19980716 resulted in the error message we were talking about. The only difference is that the seqaddr=0x17d and not the 0x17e as I usually get when booting from hard drive.
