This is the first time for me to visit this list, so don't be too hard too me if this posting doesn't fit into the common list rules. The problem appears on a machine using the pretty new ASUS CUVX-D Dual Socket 370 Motherboard, so there may be a chance for an unknown bug ;-). With NMI watchdog activated, a 2.4.x Kernel is not willing to boot on this machine, it just stops booting at a very early time, giving the latest message "activating NMI watchdog ..." and then blocking completely. Therefore, I set nmi_watchdog = 0, when the system boots properly, but leaves some crucial message in /var/log/messages: Feb 19 19:37:17 delphin kernel: testing the IO APIC....................... Feb 19 19:37:17 delphin kernel: Feb 19 19:37:17 delphin kernel: WARNING: unexpected IO-APIC, please mail Feb 19 19:37:17 delphin kernel: to linux-smp@vger.kernel.org Feb 19 19:37:17 delphin kernel: .................................... done. This is the reason for my posting in this list. This boot has been done with a self-compiled original 2.4.1 kernel, without any patches applied. With NMI watchdog activated, I could also reproduce the problem with a standard 2.4-SMP kernel from the SuSE 7.1 distribution, but booting does not lock up each time. In one from 5 trials, the system boots even with NMI watchdog activated. Here is the output of dmesg after booting the kernel 2.4.1 with NMI watchdog activated: Linux version 2.4.1 (root@delphin) (gcc version 2.95.3 19991030 (prerelease)) #1 SMP Sam Feb 17 19:51:27 CET 2001 BIOS-provided physical RAM map: BIOS-e820: 000000000009fc00 @ 0000000000000000 (usable) BIOS-e820: 0000000000000400 @ 000000000009fc00 (reserved) BIOS-e820: 0000000000010000 @ 00000000000f0000 (reserved) BIOS-e820: 000000001fefc000 @ 0000000000100000 (usable) BIOS-e820: 0000000000003000 @ 000000001fffc000 (ACPI data) BIOS-e820: 0000000000001000 @ 000000001ffff000 (ACPI NVS) BIOS-e820: 0000000000001000 @ 00000000fec00000 (reserved) BIOS-e820: 0000000000001000 @ 00000000fee00000 (reserved) BIOS-e820: 0000000000010000 @ 00000000ffff0000 (reserved) Scan SMP from c0000000 for 1024 bytes.

Afterwards, X is running properly. Using a 2.2.x kernel this behaviour doesn't appear, with a 2.4.x kernel, it is reproducable. I do not know if this is interesting for some of you guys. As the board is pretty new (just one or two weeks on the german market), this might be interesting for testing purposes. Even if I do not have the capability to help you debugging, I would be willing to test out whatever you want. Just let me know if you need further information, or send me your patches and how to apply them.
