Hello terryc, You seem to have a variety of kernel installed. Could you tell us which version works for you, and which version showed the errors?
In doubt, I would revert back to stable — not backport (bpo). So you want the
latest of the 5.10 series, which should come from security.
Care must be taken when dealing with backport kernels, as they don't usually get
shipped as a whole: the signing and verification process takes some time. Once
you're on the kernel from the stable-security channel, you can then purge all
the others you do not use. You could do that by marking all `linux-image` and
`linux-headers` as automatically installed (1) followed by a call to `apt
autoremove` (2). If your system is properly configured, it should remove all
package that:
a) are not required by another package and
b) are automatically installed
(1) sudo aptitude markauto ~nlinux-headers ~nlinux-image
(2) sudo apt autoremove
Using the automated functions of apt is of great help when trying to keep a
system somewhat clean of unwanted, or uneeded packages.
Cheers,
Ludovic

I temporarily fixed the problem by rebooting to the previous kernel,but
in investigating came across this oddity in the naming of my
installed kernels
user@system: dpkg --list | grep linux-image

Looking for clubies on why the last image doesn't fit the pattern, and
the best way to purge it.
