Bug#264339: Unknown DM device 254:0

[Giuseppe Sacco <eppesuig@debian.org>]

Package: initrd-tools
Version: 0.1.72
Severity: important

I am recompiling the kernel to be used for diskless station
with root over NFS. This machine only have SATA sil disks
so I had to recompile the latest kernels. Using both
2.6.8-rc3 and 2.6.8-rc2 I get this error message:

Setting up kernel-image-2.6.8-rc2 (nfs0) ...
Unknown DM device 254:0
Failed to create initrd image.
dpkg: error processing kernel-image-2.6.8-rc2 (--install):
 subprocess post-installation script returned error exit status 9
Errors were encountered while processing:
 kernel-image-2.6.8-rc2

I even tried to include the patch from #247054 but that didn't
solve the problem. I don't know if this may be a hint: I am working in a
chroot environment, with only /proc mounted.

Thanks,
Giuseppe
