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):

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,
