This is also true when USB access = hangs, then unplug the drive. More interesting is the third AMD laptop (dual core) had similar = problem, but it is less crashing but hanging. The core information is available at the same place (bt file is also = attached): http://www.daemonfun.com/archives/public/USB -rw-r--r-- 1 jin wheel 4668 Nov 25 23:17 bt -rw------- 1 4294967294 wheel 80074 Nov 25 22:59 core.txt.0 -rw-r--r-- 1 4294967294 wheel 72108588 Nov 25 23:09 coredump-0.tbz core.txt.0 is from savecore, and bt is I did back trace so it has = slightly more information than core.txt. The tbz file contains the kernel.symbol and all files from savecore. I will continute to dig this and I will set more coredump if new crash = happens at different place. Please let me know anything I can help debug futher before Dec 3rd. I = will on travel for a while and I do not want to hold release for another two weeks. So let's resolve the = problem before I am on travel if possible. -----Original Message----- From: Hans Petter Selasky [mailto:hselasky@c2i.net] Sent: Wed 11/25/2009 12:37 AM To: Guojun Jin Cc: freebsd-usb@freebsd.org; bugs@freebsd.org; = freebsd-stable@freebsd.org Subject: Re: 8.0-RC USB/FS problem =20 On Wednesday 25 November 2009 00:08:59 Guojun Jin wrote: > What other debug shall we turn on to analyze this problem.
