Hello, I have an AlphaStation 200 4/233 running FreeBSD 4.0-stable which I am overall very pleased with, however I have purchased an "Ultra66" ATA/66 Promise controller to replace an ISA EIDEMAXII Promise controller I had in the system. I had hoped to get away from the slower, more CPU/IRQ intensive 16 bit card since most of the files that system serves are on a large, inexpensive IDE disk. When I placed the PCI ATA/66 card in the system and booted, it crashed midway through the boot: [snip] sio1: reserved for low-level i/o unexpected machine check: mces = 0x1 vector = 0x660 param = 0xfffffc0000006000 pc = 0xfffffc00004a9c60 ra = 0xfffffc00004a9c34 curproc = 0xfffffc0000567090 pid = 0, comm = swapper panic: machine check uptime: 0s [snip] The problem is perfectly reproducible. I've tried: * updating the SRM console firmware * updating the BIOS/Firmware/whatever on the ATA/66 card * removing the ata drivers from the kernel * booting generic kernel * disconnecting hard disk from card * placing the ATA/66 card in other slots * removing other cards which might cause conflicts * updating the system to 5.0-current, and repeating Nothing seems to help. Does anyone have any suggestions?
