Poul-Henning touched this code last, so it is probably something for him to look at. I'm unsure how msleep() is getting called, however. The turnstile panic is not important, can you find the thread that went to sleep (should be pid 92279) and get stack trace for that? -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
