Anyone else seeing this on a > Compaq or any other box? I found the cause of the hangs, at least one half of the cause. While perusing through dmesg, I noticed that there were some devices probed and "found" that I had disabled in the system configuration utility. Taking a shot in the dark, I completely removed three unused drivers from the kernel (sio, ppc/lpt, psm). Now the system no longer freezes when going multi-user. WHY FreeBSD froze when going multi-user, and only multi-user, is a mystery to me. Before that I managed to get everything limping along by configuring everything by hand and running all of my services in single-user mode. :-) For the purposes of the archives, the machine in question is a Compaq Proliant ML530 using the 4/XX/2001 BIOS (XX=12, I think). This problem occurred with a 4.3-RELEASE GENERIC kernel as well, so it definately isn't something introduced by any of the recent changes we've also been talking about, but rather introduced by some version of the Proliant ML530 BIOS between December 1999 and April 2001. I suppose some changed default behaviours in the newer System Configuration Utility could have caused the problems as well. I didn't test the December 1999 BIOS with the newest configuration utility to see if the problem still occurred. Now back to the problem of the PCI BIOS and PCI interrupt routing on these beasts. :-) -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet - Available for IA32 (Intel x86) and Alpha architectures - IA64, PowerPC, UltraSPARC, and ARM architectures under development - http://www.freebsd.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
