There aren't any errors in syslog, but after the boot partition is mounted, every add-on the kernel subsequently attempts to load fails with "Not an executable", so it seems as if the I/O 'succeeds' but doesn't return the expected data in some way. Anything I can do to help track this down?
I can reproduce the issue, but ATM my understanding of the code simply isn't good enough and I currently don't want to invest the time to get there. I think the first thing is to clean up the code (get rid of the {read,write}_pages() hooks) and fix a longstanding issue, the missing distinction between uncached and cached I/O, which currently makes it a bit confusing what the respective VFS functions should actually be doing.
