This version no longer compiles into the -current kernel. This problem was also affecting scsi scanners and according to a message I got from Amancio Hasty on the 5th of April, that this has been fixed for the scanner problem. >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
