This was observed on two separate machines with different hardware configurations and a DE201 NIC, and was also reported on -questions by others with different DE20x cards and setups. The cards I used to test were known to work under 3.x. Everything from 4.0-R to the current -STABLE displays this behaviour. The machine boots up fine, recognizes the card and crashes as soon as ifconfig(8) is run. Fatal trap 12: page fault while in kernel mode fault virtual address = 0x0 fault code = supervisor read, page not present instruction pointer = 0x8:0x0 stack pointer = 0x10:0xce323d70 frame pointer = 0x10:0xce323d84 code segment = base 0x0, limit 0xffff, tytpe 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 168 (ifconfig) interrupt mask = net trap number = 12 panic: page fault >How-To-Repeat: Install DE20x NIC on 4.0 machine and rebuild kernel with le driver. Manually run ifconfig on le0 and watch it crash and burn. >Fix: Sorry, no fix. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
