USB umass kernel panic

[Guido Falsi]

Hello,

In the last few days I've been experiencing a reproducible kernel panic 
whenever plugging in my new digital camera (Pentax Optio Z10). Tried 
with a freshly cvsupped system too. I'm using 7.0.

Here is a manual transcript of the panic message, I have some core dumps 
too, if needed. They're a little big as usual.

umass0: <PENTAX PENTAX Optio Z10, class 0/0, rev 2.00/1.00, addr 2> uhub3
(da0:umass-sim0:0:0:0): unsupported block size 0
(da0:umass-sim0:0:0:0): lost device
panic: kmem_malloc(-1407700992): kmem_map too small: 14807040 total 
allocated
uptime: etc. (I thought the rest is not really needed)

I;m available to give any information required to get into the problem. 
Perhaps the camera is doing something strange(block size 0????) but the 
panic is surely out of place...

Thank you in advance for any help.
