freebsd stable - Feb 2009 - FREEBSD 7.1-STABLE crashes when trying to mount USB device of solaris UFS filesystem

Hi everybody,

today I met the following problems on my freebsd box. I had a USB stick 
of opensolaris bootable USB image and tried to mount it on my fbsd box. 
The first time, when I tried to mount the usb device, my system freezed 
and then rebooted giving me one core in my dumpdev. When I tried to redo 
the mounting, the kernel informed me that the filesystem needed to be 
fsck'd before mounted, or else I should have tried to mount it ro. When 
I tried to mount it with the read-only option set, the kernel panicked 
once more, and another core was dumped on my dumpdev.

Recently, I keep having problems with USB disks. For instance, yesterday 
night I left an msdosfs USB partition mounted on my pc. This morning, 
the first thing I did was to check my emails through Thunderbird. When I 
clicked on the first unread message, everything freezed. There was no 
keyboard or mouse interaction whatsoever (both USB devices), and I had 
to shutdown my box via the shutdown button (hence and no core dumped, 
unfortunately). Another time, my kernel panicked exactly when I 
connected my USB external disk to my box while the kernel was loading.

Since my box crashed thrice today (once due to the 
since-yesterday-mounted-msdosfs filesystem, and twice due to the 
opensolaris ufs filesystem) I decided to send you this bug report; so 
here is the thing:

1)
# uname -a

FreeBSD myhost 7.1-STABLE FreeBSD 7.1-STABLE #0: Thu Jan 15 21:47:42 EET 
2009     root@myhost:/usr/obj/usr/src/sys/KERNEL  i386

2) My differences from GENERIC are:
cpu             I686_CPU               # only i686 support


options         SCHED_ULE         # I think now it's the default
options         QUOTA
options         MAC
options         AUDIT

options         KDTRACE_HOOKS
options         DDB_CTF
options         SMP
device          apic

device          pf
device          pflog
device          pfsync

device          atapicam
options         VESA


3) And my three core dumps are:

------------------------------------------------------------------------------------
vmcore.2:  MAY be the core created when I plugged  in the USB  disk 
while the kernel was loading (sorry guys, not sure, hadn't payed too 
much attention at that moment, and don't remember if this is the correct 
dump):

vmcore.3 is the first core created when I tried to mount opensolaris ufs 
for the first time (without using mount -o ro)

And vmcore.4 was created after I tried to mount the same filesystem with 
the ro option set:

I will csup my box to the latest freebsd-stable and see if the problems 
persist. If not, I hope this message will help somebody to find some 
solution.

Thank you all for your help in advance,
regards,

George Mamalakis
