Nope. Just
ata7: [ITHREAD]^M
^M
^M
Fatal trap 12: page fault while in kernel mode^M
cpuid = 0; apic id = 00^M
fault virtual address = 0x28^M
fault code = supervisor read, page not present^M
instruction pointer = 0x20:0xc055b69c^M
stack pointer = 0x28:0xfcb0aabc^M
frame pointer = 0x28:0xfcb0aaf8^M
code segment = base 0x0, limit 0xfffff, type 0x1b^M

processor eflags = interrupt enabled, resume, IOPL = 0^M
current process = 3725 (atacontrol)^M
trap number = 12^M
panic: page fault^M
and approx 15 seconds of wait between ata channel detection and the panic.
