Hiten, You're aborting on an assertion that no longer exists in vm_map.c. This appears to be a case where your new kernel is based upon the new vm_mmap.c but an old vm_map.c.
Please make sure that both vm_map.c and vm_mmap.c are updated and try a "make clean" before building your kernel. Regards, Alan To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
