>Description:
msk0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500

ntfs-3g -o noatime,nosuid,nomand,users,noauto /dev/da0p1 /mnt
=> kernel panic (panic: vm_fault: fault on nofault entry...)

via another network adapter:
rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
all is ok! mounts without any errors.

all seems to be okay.
Same result with 7.4-PRERELEASE (22 Feb 2011) and fixed(watchdog) msk driver, ported back to 7.2

/dev/da0p1 - virtual iscsi device with ntfs filesystem.

>How-To-Repeat:
attach iscsi device with ntfs filesystem and mount it with ntfs-3g via msk network adapter
>Fix:
change network adapter
