Re: New cloop-src for the 2.6.22* kernel?

[Fabian Schulte <fabian.schulte@nexgo.de>]

Hi Tapani,

I had some spare time today and tried the latest stable linux-2.6.22.5
source with the cloop-src package version 2.04-1+eb.1-7 from Etch. It
processed fine after applying the following patch to the cloop-source
tree.

I experienced the same bearing, with the CPU waiting for I/O infinitely,
on mount, alas!
