Package: linux-image-3.2.0-4-amd64
Version: 3.2.39-2

I'm using a reasonably vanilla "testing" distribution.
The i915 module would not load, either at boot or using "modprobe -a i915". The error message on the command line is as follows. 

  FATAL: Error inserting i915 (....): Invalid argument

In dmesg it is as follows.

[    3.227711] i915: disagrees about version of symbol i2c_bit_algo
[    3.227766] i915: Unknown symbol i2c_bit_algo (err -22)
Consequently, the xorg intel driver (for intel i3 2100, with HD 2000 graphics) wasn't loaded, and X11 fell back to VESA. I reverted to an earlier kernel/modules set and things work fine. Reverting was somewhat of a chore as when the new kernel/modules set was installed it completely replaced the earlier one. I would rather that it had not. 

Best wishes,
Bob

This is not a kernel bug - it indicates that modprobe didn't load all of
i915's dependencies first (specifically i2c-algo-bit).

Since this works for everyone else, I suspect that modprobe's dependency
information got corrupted somehow.  But all the evidence of that has
almost certainly been wiped out when you reinstalled the old package.
So there's nothing useful I can do here.

Upgrade again and I bet the package will work fine.  If not, reopen this
bug and attach /lib/modules/3.2.0-4-amd64/modules.*.

Ben.

It is easier to change the specification to fit the program than vice versa.
