[Bug 22220] Re: Correct modules for I2O-based raid are not loaded

hw-detect 1.32ubuntu8 uploaded to dapper-proposed for approval. This
will also need a trivial debian-installer upload afterwards to rebuild
the initrd against it.
** Description changed:
Ubuntu 5.10 Preview experiences a system panic w/ I2O based raid controler at
kernel boot after controller is detected. Current controller that this is
experienced on is a Adaptec 2400a Hardware Raid (IDE). I do not have any other
I2O based controllers on which to test this.
5.4 did not experience this (we currently are using it), so this must be a
regression in the preview version.
Details for hw-detect dapper proposed update:
The installer offers a menu of disk drivers when disks are not
automatically detected. This list fails to include the drivers from
drivers/message/fusion and drivers/message/i2o (mpt* and i2o_*). Thus,
users of these devices have no obvious manual fallback if automatic
detection fails.
The bug was addressed in hw-detect 1.33 (in edgy) by adding these
directories to the list of directories to be searched for drivers to
offer, and adding a guard in case either directory doesn't exist.
+ A proposed patch for dapper is linked here:

You can reproduce this bug by removing the kernel module responsible
for your disk from the running installer before it has a chance to load
it (be quick!), and looking at the list of disks offered. Alternatively,
it might be easier to boot in VMware with no disks attached.
I haven't yet thought of any regression possibilities here, but they
ought to be limited to the path where no disks were automatically
detected.
** Changed in: hw-detect (Ubuntu Dapper)
