Hello community, Iam currently using: ami-b55f99dc I downloaded ports and src from a cvsup server and proceeded to do a make buildworld .. This one went well but took over 24 hrs :) The problem is that after that I did make buildkernel and it errors: usr/src/sys/dev/usb/usb_process.c: In function 'usb_process': /usr/src/sys/dev/usb/usb_process.c:104: error: too few arguments to function 'kthread_suspend_check' *** Error code 1 Stop in /usr/obj/usr/src/sys/GENERIC. *** Error code 1 Stop in /usr/src. *** Error code 1 Stop in /usr/src. Am I doing something wrong? Iam trying to go from RELEASE to STABLE . Are there any issues with this compilation under ec2?
