Dear listers, We currently found that amd frequently cores dump while loading is high (about 4~5) after we upgrade world & kernel from 7.0-RELEASE to 7.1-PRERELEASE. I have read -stable and svn log of 7-STABLE, but can not found a report or a solution. Did anyone have the same issue? Thank you very much. # uname -a FreeBSD bsd1 7.1-PRERELEASE FreeBSD 7.1-PRERELEASE #8: Fri Dec 19 22:44:22 CST 2008 root@bsd1:/usr/obj/usr/src/sys/KERNEL amd64 # dmesg pid 51645 (amd), uid 0: exited on signal 11 (core dumped) pid 52077 (amd), uid 0: exited on signal 11 (core dumped) pid 52083 (amd), uid 0: exited on signal 11 (core dumped) pid 53876 (amd), uid 0: exited on signal 11 (core dumped) pid 56444 (amd), uid 0: exited on signal 11 (core dumped) # gdb `which amd` /amd.core GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
