As the subject says, does mount_ntfs or USB hard disks work on Alpha?

I have one which is formatted NTFS (from WinXP) and I'm trying to mount it 
on my Miata which is running 4.11-STABLE.  I have all the relevant bits 
compiled into the kernel, and I can see the umass(4) driver attach when the 
device is plugged into the on-board USB port (the ntfs kernel module is 
loaded as well):

Jan 13 14:07:08 erwin /kernel: umass0: Genesys Logic USB TO IDE, rev 
2.00/0.02, addr 2
Jan 13 14:07:08 erwin /kernel: da2 at umass-sim0 bus 0 target 0 lun 0
Jan 13 14:07:08 erwin /kernel: da2: <TOSHIBA MK4025GAS 0811> Fixed Direct 
Access SCSI-0 device
Jan 13 14:07:08 erwin /kernel: da2: 650KB/s transfers
Jan 13 14:07:08 erwin /kernel: da2: 38154MB (78140160 512 byte sectors: 64H 
32S/T 38154C)

Trying to mount with "mount_ntfs /dev/da2s1 /mnt" causes a panic and a reboot.

Here's the details of the panic:

fatal kernel trap

         trap entry = 0x4 (unaligned access fault)
         a0         = 0xfffffe00011cf061
         a1         = 0x2d
         a2         = 0x1f
         pc         = 0xfffffe00011f574c
         ra         = 0xfffffe00011f5b38
         curproc    = 0xfffffe000bfbc880
                 pid = 2156 , comm = mount_ntfs

panic = trap

cheers,
rob
