HEADSUP!!! USB MFC committed

[Cordula's Web]

Hi Julian,

this USB MFC broke my CASIO QV-4000 digicam downloads, which worked
very well just before.

umass0: CASIO product 0x1001, rev 1.00/10.00, addr 2
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <CASIO DIGITAL_CAMERA 1.00> Removable Direct Access SCSI-0 device 
da0: 150KB/s transfers
da0: 1027MB (2104704 512 byte sectors: 255H 63S/T 131C)
(da0:umass-sim0:0:0:0): READ(10). CDB: 28 0 0 1a f5 22 0 0 38 0 
(da0:umass-sim0:0:0:0): ABORTED COMMAND asc:4e,0
(da0:umass-sim0:0:0:0): Overlapped commands attempted
(da0:umass-sim0:0:0:0): READ(10). CDB: 28 0 0 1a f5 22 0 0 38 0 
(da0:umass-sim0:0:0:0): ABORTED COMMAND asc:4e,0
(da0:umass-sim0:0:0:0): Overlapped commands attempted

Mounting /dev/da0s1, ls et al. still works well, but as soon
as I start downloading the files with, say, "cp -Rv /mnt/* .",
the cp command hangs hard after having copied 5 or 6 small files.
The only way out is to turn the camera off, get a few errors:

umass0: CBI reset failed, IOERROR
umass0: CBI bulk-in stall clear failed, IOERROR
umass0: CBI bulk-out stall clear failed, IOERROR
vnode_pager_getpages: I/O read error
vm_fault: pager read error, pid 7337 (cp)
umass0: at uhub0 port 1 (addr 2) disconnected
(da0:umass-sim0:0:0:0): lost device
umass0: detached
umass-sim:0:0:0:func_code 0x0901: Invalid target (target needed)
(da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x39,
			scsi status == 0x0
umass-sim:0:0:0:func_code 0x0901: Invalid target (target needed)
(da0:umass-sim0:0:0:0): removing device entry

and then umount manually.

Please help.

Cheers,
-cpghost.
