Bug#440206: multipath-tools: installing multipath tools causes mkinitramfs to generate, an initrd which does not boot

[Take]

I've experienced this same issue with fresh Lenny installation. I
installed multipath tools over fresh installation (with other packages)
and the machine won't boot after that. Messages on the screen are the
same than Ian reported few years ago. I don't have exact copy at hand,
but basically I get 'Discovering multipaths...' and after that mount
says 'Device or resource busy.'

After I booted into rescue shell and did 'apt-get --purge remove
multipath-tools && update-initramfs -u' the machine boots up just fine.

I've confirmed that this is reproducible, so I'd say that this bug isn't
fixed.

The machine is Dell r610 with LSI RAID controller:
