This is a warning, not a panic (which would stop the kernel
completely). Still, I assume that the permission denial makes it
impractical to use the system with hidepid enabled.
This problem was not caused by any of the fixes in the latest update,
but by a fix in 3.2.93 that meant I should have updated the backport of
the hidepid feature. However, I added a binary compatibility patch to
avoid problems like this with any out-of-tree users of the API, and
that hid the problem until I bumped the ABI number and removed all the
binary compatibility patches.
I'll fix this in the next upload. As a temporary measure, you can
rebuild the kernel package with the attached patch, by following the
instructions here:
