The problem occurs because the disk flush is async and no time is given for this to happen. >How-To-Repeat: Shutdown a box with a hptmv based controller with power off. >Fix: Apply the following patch which adds a 5 second delay after calling flush. Note: the fix is only relavent for i386 as there is no source for amd64, which is also affected. I've informed Highpoint of the issue but as yet no updated driver has been released. --- entry.c.orig Tue Jun 21 13:23:05 2005 +++ entry.c Tue Jun 21 13:27:38 2005 @@ -2157,6 +2157,10 @@ return (EINVAL); - EVENTHANDLER_DEREGISTER(shutdown_final, pAdapter->eh); FlushAdapter(pAdapter); + + /* give the flush some time to happen */ + DELAY( 1000 * 1000 * 5 ); + + EVENTHANDLER_DEREGISTER(shutdown_final, pAdapter->eh); return 0;
