This seems to be a problem with all the DMC-LCx cameras. They don't
handle the SCSI "Allow Medium Removal" command correctly.
You can fix this in either of two ways. First, you can edit your kernel
source by hand and rebuild the SCSI driver. The file you need to change
is drivers/scsi/scsi_devinfo.c. In that file you will find a long list of
device entries, including a couple marked MATSHITA and DMC-LC5 or
DMC-LC40. Either change one of those lines, or add a new line of your
own, that says DMC-LC33.
Alternatively, you can take an equivalent action at runtime without
changing the kernel at all. Some time after the scsi_mod module is
loaded, but before you plug in your camera, do this (as root):
echo 'MATSHITA:DMC-LC33:0x80400' >/proc/scsi/device_info
