Hi all, Been having problems with my Tyan Thunder i7500 (S2720) dual Xeon running -STABLE: it's hanging every couple of days. I couldn't find any specific fixes on the lists, but I did come across some instructions about breaking into the debugger from a serial console. I built a kernel with the following options: DDB, KDB, WITNESS & BREAK_TO_DEBUGGER (INVARIANTS wouldn't build). When it hangs, there seems to be no response - no network activity (pings), no response from the keyboard/mouse, but I *am* able to break into the debugger. I ran "show pcpu", "ps", "show threads", "show alllocks", "show lockedvnods" and saved the output. What do I do with the data to further troubleshoot my problems? Thanks.
