Even if this patch changed the kernel module ABI (which it doesn't) that should only result in being unable to load new modules until you rebooted into the new kernel. Each symbol that's exported to modules has a 'version' that is a hash of related type definitions, and the kernel's module linker requires both name and version to match. This certainly seems like another bug. However I don't think we'll be able to do anything about it without some kind of crash log. If your computer boots with EFI then the kernel might have been able to save a crash log in flash. The reportbug script for the kernel knows how to read this back (it appears in the /sys/fs/pstore directory), and will prompt you to include it. Ben. -- Ben Hutchings The world is coming to an end.
