Hi Brad 


I downloaded yesterday grsec 2.1.4 + 2.6.11.5 kernel.(patch applied OK)+ 
user space utils last version.
i hoped you fixed the oops i reported 1-2 weeks ago(rmmod ide-scsi ) 

Instead all i got was a taotal surprize.
The patch is very BUGGY. 

The kernel segfaults very often(but not freezing ) at different processes.
For ex .... quotaon,cupsd,even reboot. 

I'm sending in attach the oops fromm qutoaon and you can retrieve my system 
settings (i hace FC3) from the attach of the last bug-report. 


Thanks. 

PS: And plz fix the rmmod ide-scsi oops before the next release
Kudos
