VMAX USB-STORAGE - kernel deadlock

VMAX USB-STORAGE - kernel deadlock

[Michal Semler]

Hi,

my friend bought usb flash disk VMAX/USB2.0/0404 version.
Under WinXP it works, but not under Linux.
There is 1 vfat filesystem, but linux reports 4 and when I try mount one, 
kernel goes to deadlock. System reports bad size too.

Tested 2.4.26, 2.6.6

Here is output:

SCSI subsystem initialized
Initializing USB Mass Storage driver...

Try mounting /dev/sda instead of a partition.
