I followed the guidelines in mounting a USB drive, which are explained in the FreeBSD doc:
I tried everything to umount USB-drive normally but without success and in the end tried a forced umount:
which resulted in a kernel panic.
Then I retried something different:
This worked fine for at least two machines.
What am I missing that I received a kernel panic?
PS: The kernel panic resulted on a machine on which the kernel had been recompiled for dtrace. In this case the probes were not loaded. (An experiment with dtrace already resulted in a kernel panic.)
Code:
% mount -t msdosfs -o -m=644,-M=755 /dev/da2s1 /mnt/username
I tried everything to umount USB-drive normally but without success and in the end tried a forced umount:
Code:
# umount -f /mnt/username
Then I retried something different:
Code:
# mount -t msdosfs /dev/da2s1 /usr/home/username/USB_drive/
Code:
# umount /usr/home/username/USB_drive/
This worked fine for at least two machines.
