Hi folks! Back from a one week vacation, I immediately updated my machine to BETA 7. Before I left, my machine had panics serveral times a day. Since BETA 6 the panics are gone but the machine locked up a few times (experienced two days before I left for a week). The machine freeze has been mostly while hanging up or shortly after a ppp (userland) connection has been hang up. Now I've updated to BETA 7 and the machine seem to lock up faster. The machine freezes most times while having an established ppp connection to the public internet. The machine is acting as a router, dial-up client, proxy, mailserver, webserver etc. etc. When the machine locks up, there's no console or network response from the machine. The only way out is the reset switch. One of my guesses has been that either i4b or userland ppp is causing the machine freeze. To figure out if that might be the case, I've set up a 2nd machine (releng_4) acting as a dial-up client (i4b/ppp) and router. The 2nd machine is now being used as a default route for the server machine. Since using that test setup the server machine didn't had a lockup. So my guess might be probably right to have a problem somewhere at i4b or user-ppp in releng_5. How does one debug a dead machine? Is there any way to get a backtrace or call the debugger while the machine has been frozen? Thanks, Volker -- GPG/PGP fingerprint: FF93 13A1 2477 B631 E953 06DF 4C49 ADD9 E4BF 79B1
