Oops on module load - sysfs_create_group

Reported by: vz-madwifi@zeitlins.org Assigned to: mentor
Priority: major Milestone: version 0.9.5
Component: madwifi: 802.11 stack Version: trunk
Keywords: Cc:
Patch is attached: 0 Pending:

Description

I've built the module from the svn revision 2650 and did "make install" after uninstalling all the previous madwifi versions. Loading it results in a kernel crash, here is the syslog output:
