I see very similar bug that appears in kern_clocksource.c:579. The per cpu et_hw_mtx contains some garbage data before mtx_init(), it seems that something corrupts the kernel memory after teh kernel is loaded. Unfortunately, I did not succeed to catch the intruder. It is strange, that hw breakpoints does not help. -- Have fun! chd _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
