Updating Linux host software causes host OS crash => Fixed in SVN

Description

I am currently automatically picking up updates from you Debian repositories.

When the latest update arrived, it attempted to recompile its kernel module and then replace the module whilst my m/chine was up and there were active VMs. This caused a crash of the host system. (Total freeze, reset button required.) Fortunately no important data was lost, though minor use of backups was required.

This is essentially a show stopper as an automated process can, without warning, knock over the host machine.

The question is how this can happen. If you have running VMs then it is normally not possible to remove the kernel modules. Did you enable something like CONFIG_MODULE_FORCE_LOAD in your kernel config?

Good point. Am running a stock debian kernel. config snip follows:

CONFIG_MODULES=y CONFIG_MODULE_FORCE_LOAD=y CONFIG_MODULE_UNLOAD=y CONFIG_MODULE_FORCE_UNLOAD=y

Perhaps you could check to see if there are any processes running? Will also be raising bug over at debian.

I have had a look at the actual .deb package. I recall it barreling through without actually asking if it could replace the kernel, though I can't find where it would insist on that in the source. Its possible that it is using an old question answer regarding whether or not it should build a module rather than asking again if its OK to chance its luck.

Many people run aptitude update/safe-upgrade regularly for patches and fixes. It needs to clearly signal its intentions so there are no mishaps.

Fixed in SVN. Actually we didn't properly lock the kernel module as long as an internal network was active. See r17344 + r17375.
