Recently my 2.6.22.13-0.3-default SUSE kernel has stopped automatically
mounting my USB disks and thumbdrives under /media. The strange thing is
that this worked just fine up till recently and occasionally still works
again after a reboot. All the plugged-in USB devices appear to be
visible to the kernel (see 'lsusb' and 'fdisk -l' output below), but
they simply won't mount every time on boot or when I hotplug them.
However, I _can_ mount them manually without an issue. Also, I've made
no changes to /etc/fstab for ages that might account for this. I've seen
some Google references to wrong permissions on USB devices that might
generate this warning, but none of them sound quite right to me here.

Here's an excerpt from dmesg at boot time where it complains about one
of the USB storage devices and then won't mount it under /media with the
"VMBlock warning:..." message:

Any help would be much appreciated. This has gotten to be quite annoying.

TIA,
