           Summary: When a kernel ipkg is released, "ipkg upgrade" breaks
                    kernel modules
           Product: OpenMoko
           Version: 2007.2
          Platform: Neo1973
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: kernel
        AssignedTo: laforge at openmoko.org
        ReportedBy: gnu at openmoko.toad.com
                CC: buglog at lists.openmoko.org

Ipkg can't upgrade a kernel (it sits in its own partition), but it can upgrade
kernel modules (which are in the normal filesystem).  So when somebody releases
a new kernel and modules, the new modules get loaded by "ipkg upgrade" and then
they don't work with the old kernel.

I flashed the 2007.2 release, then after getting my USB networking gatewayed
properly, did "ipkg update && ipkg upgrade".  This installed new kernel modules
(and maybe tried to install a new kernel into the ordinary filesystem).  This
broke my kernel modules (e.g. mounting vfat filesystems didn't work; the sound
stopped playing at reboot; etc) until I was able to figure out where to find the
new kernel and manually flash it into the kernel partition.

How to fix this?  An obvious way would be to make the kernel ipkg install the
new kernel into the kernel's proper partition.  Failing that, it may be possible
to circumvent the problem by administratively never releasing new incompatible
modules into a repository where "ipkg update" will install them for ordinary
naive users.
