The kernel panics when the SCSI bus is run any faster than 80 MB/s. It drops into the debugger on boot, with 5.1 beta. In 5.0 release, it would give an error message about an invalid block and lockup. >How-To-Repeat: Use a multi-processor motherboard that also has U320 SCSI, and a u320 SCSI hard drive. Compile and install a SMP kernel from GENERIC, uncommenting the two SMP lines. reboot, during the reboot set the SCSI bus in the SCSI BIOS to full speed, 320 MB/s Just after the SCSI devices settle you will fall into the debugger. If you reset the server and start to reboot, you can set the SCSI bus speed to 160 MB/s in the SCSI BIOS. You will have the same result as you did at 320 MB/s If you reset the server ans start to reboot, you can set the SCSI bus speed to 80 MB/s in the SCSI BIOS. The server will boot and run fine. >Fix: The work around is to set the bus speed at no faster than 80 MB/s. >Release-Note: >Audit-Trail: >Unformatted:
