 Posted: Mon Sep 20, 2010 1:39 pm Post subject: loop-aes module "Invalid module format"??? [SOLVED |
 |
|
I emerged loop-aes with no problem at all, but when I 'modprobe loop' I receive the following message:
| Code: |
FATAL: Error inserting loop (/lib/modules/2.6.35.3/block/loop.ko): Invalid module format
|
I googled a bit, but as unable to find anything helpful.
Anyone have any idea what's going on?
Here's my emerge --info output just in case it's helpful to anyone:

Solution: turn loopback support off in the kernel. It can't coexist with loop-aes.

Try updating your os-headers to match your currently running kernel. See Gentoo Packages /package/sys-kernel/linux-headers. Since you are running an ~arch kernel, I'll assume you know how to do this. After updating headers recompile kernel and try reinserting module.

Thanks for your suggestion! I updated my linux-headers to match my kernel version and rebuilt. I still see the same behavior.
Looking at the output of 'emerge loop-aes', I'm under the impression that it compiles against /usr/src/linux rather than the separately packaged linux-headers, ut I didn't dig further to confirm that's what's happening. |

flatelin,
Try | Code: | | ebuild -1 module-init-tools |
if that fails rebuild and reinstall your kernel, starting from make clean.
You have either changed gcc between making the kernel and loop-aes or changed another key configuration option that requires a full kernel rebuild.

I've rebuilt my kernel starting from 'make clean' and I'm still seeing the exact same behavior.
I'm in the process of rebuilding my entire toolchain (gcc, glibc, binutils, libtool) and when I'm finished, I'll rebuild my kernel starting from a 'make mrproper' and then rebuild loop-aes and see if that gets me anywhere.
I'm a little mystified as to what's going on here. For the last several years, whenever I build a new kernel, I just re-aim /usr/src/linux and rebuild loop-aes. I've never had any problem before this. |

flatelin,
Check ensure you are running the kernel you think you are and it was built at the date/time you remember rebuilding the kernel.
If thats ok, are there any errors building loop-aes ?

As another branch of thought here, since Neddy and I are on the same page on Kernel behavior, did you update /boot/grub/grub.conf to point to your new kernel? Also, post the output of ls -al /usr/src/
As a side note, a few tree updates back the stable kernel was bumped back from 2.6.35 to 2.6.34, but to confirm that is part of our problem, the listing will tell me. For help rebuilding the toolchain see the emerge wrapper in my signature. While it's a little old, it does it's job.

Okay, I've got it working now.
The issue was that I was building loopback support into my kernel. Apparently you can't have loopback both in the kernel and provided by loop-aes. Rebuilding the kernel without loopback support fixed my issue.
Thanks for all your help! |
