-----BEGIN PGP SIGNED MESSAGE----- Hi, folks. I was hoping that someone would take a look at kern/11222, which has been open since I submitted it in April. The problem it addresses is that MFS buffers that are dirty when the reboot syscall is made are never cleaned because the reboot call never calls sleep, so the user-level process backing the MFS can never run to mark the buffers as clean. There are two patches with the pr, one from the date it was submitted which specifically detects MFS buffers and calls sleep if they're present, and one which replaces the DELAY calls in reboot with tsleep calls. The second was at the suggestion of Matt Dillon, who looked at the patch and PR in late April, but apparently hasn't had more time to look at it (yes, I pinged him). Is there someone else who is knowledgable about the reboot sequence who's willing to have a look at these patches? I've been running the second patch (removes DELAY) on my 3 3.1-RELEASE and 3.2-RELEASE machines (2 desktops and a laptop) without incident since April. I think they're pretty stable. Of course I'm happy to discuss the patches in tdetail with anyone willing to look at them. Thanks! - ---------------------------------------------------------------------- Ted Faber faber@isi.edu USC/ISI Computer Scientist http://www.isi.edu/~faber (310) 822-1511 x190 PGP Key: http://www.isi.edu/~faber/pubkey.asc -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBN4Jj8ob4eisfQ5rpAQHvvgP/fCJtGuQnoQjnc9/BXlLwvV9+5kzj1Imr TPk1gIQNwGkTDtqFnznm9nXV83baD7rZkKajb+O7NcqBoiohI/5Ir99PNhjiwxgc Ff5WSlE1ezO2V6Kp+wJjalB5ASXlekfWdwaFdgF4HihbAeRkJ8u3tvzuxiutjqeF DHzh8AwkO5I= =jZtL -----END PGP SIGNATURE----- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
