Hi,

I ran into an issue with modprobe ocfs2 causing kernel panic. This only happened when FIPS is enabled via fips=1 in kernel boot parameter.

The error message is  
Kernel panic - not syncing: Module verification failed with error -126 in FIPS mode  
Pid: 3388, comm: modproble Tainted: G X 3.0.76-0.11-default #1

Hi guangsu,

if no-one can offer an immediate solution, I’d like to take this to my SUSE contacts. Could you please tell us which SLES this is, if the latest patches are applied and if you’re using HAE (as opposed to having installed OCFS2 from other sources)?

Regards,  
Jens

Hi Jens,

I am using SLES11 SP3 and SLES11 SP3 HAE. The OCFS2 is coming from the HAE.

Thanks

Hi Guang,

I’ve noticed that 3.0.80 is available in the update channels… have you tried that already?

Thanks

Hi Guang,

I have been asked if you could please provide the output of “modinfo ocfs2.ko” and let me know if the machine was booted in UEFI secure boot mode.

Regards,  
Jens
