Sorry, I meant I'd follow up with Matthew Gilbert. Also, I've been trying to track down a crash in nfs_node that Nils Holland has been having - he appears to have the same chipset and could have the same problem, and he can reproduce the panic very consistently within a few hours. Brady has an older chipset. Are there any known problems with this chipset? pcib1: at device 1.0 on pci0 pci1: on pcib1 isab0: at device 7.0 on pci0 isa0: on isab0 atapci0: port 0xe400-0xe40f at device 7.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
