Attached is the screenshot (sorry, I'm running this command from an initramfs console under virtualbox and this was the fastest way). > Please, send also the output of "modinfo squashfs" (or "modinfo > /lib/modules/3.0mamba/kernel/fs/squashfs/squashfs.ko" if it doesn't > work). I couldn't do this from the initramfs environment because modinfo is missing, by the way I checked that the squashfs.ko files are identical in both environments. # modinfo squashfs -k 3.0mamba filename: /lib/modules/3.0mamba/kernel/fs/squashfs/squashfs.ko license: GPL author: Phillip Lougher <phillip@xxxxxxxxxxxxxxx> description: squashfs 4.0, a compressed read-only filesystem depends: vermagic: 3.0mamba SMP preempt mod_unload PENTIUMIII > > What's the output of "uname -r"? 3.0mamba. It is in the screenshot as well. These information don't seem to produce a solution to me, and as I said before this only happens in initramfs environment, a fully running system with same kmod and kernel does not produce the problem.
