[-- Attachment #1 --] Most crash had the same back trace. 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 On Wednesday 25 November 2009 00:08:59 Guojun Jin wrote: > What other debug shall we turn on to analyze this problem. Are you able to extract the panic message? Try enabling dump on the swap partition. --HPS [-- Attachment #2 --] DUMP: 13.26% done, finished in 0:32 at Wed Nov 25 22:28:23 2009 DUMP: short read error from /dev/da0s2d: [block 54599860]: count=1024, got=0 DUMP: short read error from /dev/da0s2d: [block 78464704]: count=7168, got=0 DUMP: 20.55% done, finished in 0:38 at Wed Nov 25 22:39:22 2009 DUMP: 25.95% done, finished in 0:43 at Wed Nov 25 22:48:46 2009 DUMP: 26.00% done, finished in 0:57 at Wed Nov 25 23:08:07 2009 DUMP: short read error from /dev/da0s2d: [block 263077536]: count=3072, got=0 DUMP: 26.03% done, finished in 1:11 at Wed Nov 25 23:27:19 2009 DUMP: 26.06% done, finished in 1:25 at Wed Nov 25 23:46:34 2009 DUMP: 26.10% done, finished in 1:39 at Thu Nov 26 00:05:46 2009 15 /var/crash: vi core.txt.0 16 /var/crash: kgdb /boot/kernel/kernel.symbols vmcore.0 GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
