Dear all,
when I tryied to mount an iso image over network (using samba) my computer unexpectedly crashed.
I issued this command : mdconfig -a -t vnode -f /path/to/my/file/mounted/on-local-machine
and since that kernel crashed, no ping response, nothing at all. I've been connected to this machine via ssh. I use 5.0 RELEASE with GENERIC kernel on P3/1 Ghz, 128 MB RAM.
It happens again when I issue same command and therefore I tryied to add "dumpon=Yes" to my /etc/rc.conf, but nothing has been written to /var/crash. So I enclose message from screen:
Fatal trap 12 : page fault while in kernel mode faukt virtual address = 0x0 fault code = supervisor read, page not present instruction pointer = 0x8:0xc1c50d4a stack pointer = 0x10:0xcd1b8718 frame pointer = 0x10:0xcd1b8738 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def31 1, gran 1 processor eflags = interrupt enabled, resume,IOPL = 0 current proccess = 549 (mdconfig) trap number = 12 panic:fault page
I'm seeing the same thing with 5.1-RC1. Tried to mount an ISO image with mdconfig -a -t vnode -f isofile -u 0 and FreeBSD immediately panic-ed. The iso file resided on a samba mount, which I had mounted with mount_smbfs. I'll try cp-ing the file to my local UFS filesystem, and then try mdconfig, and see if I get the panic again.
