The only cure seems to be a reboot. >How-To-Repeat: It appears hard to duplicate when required but has happened twice, both times the Matrox Meteor was in use and the "/kernel: meteor0: ioctl: tsleep error -1" appeared a few minutes before. >Fix: None known. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
