The system is running GENERIC off the 5.0-RC2 ISO's (i386). Here's the output: Fatal trap 12: Page fault while in kernel mode fault virtual address = 0xf0 fault code = supervisor read, page not present instruction pointer = 0x8:0xc02becef stack pointer = 0x10:0xcdc4abc8 frame pointer = 0x10:0xcdc4abe0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 495 (cp) trap number = 12 panic: page fault fsck_ufs was running in the background during the above. When I allowed fsck_ufs to complete and retried, the copy operation completed. As a side note, the system seems vulnerable to page fault panics while the background fsck_ufs is running after a hard crash. I've had several in the past 20 minutes in the cron process, to the point where I'm right now in the 5th iteration of a panic/reboot loop without touching the system. The hardware itself was stable under 4.7. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
