Hi,
Using a RELENG_6_0 from this morning, I got the panic message :
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x24
fault code = supervisor read, page not present
instruction pointer = 0x20:0xc061de49
stack pointer = 0x28:0xcad86afc
frame pointer = 0x28:0xcad86b2c
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 = 1097 (ntpd)
trap number = 12
panic: page fault
Uptime: 11m10s
Dumping 190 MB (2 chunks)
the backtrace is there :
http://p.mat.cc/x
and the dmesg is there :
http://p.mat.cc/z
the GPS USB device is seen on 6.0 as :
ucom0: vendor 0x067b product 0x2303, rev 1.10/2.02, addr 2
on 5.4 it was :
ucom0: Prolific Technology PL2303 Serial adapter (ATEN/IOGEAR UC232A), rev
1.10/2.02, addr 2
I've saved the kernel.debug and vmcore.0 if someone is interested, and I'd be
willing to try patches :-)
