On my side this was a big step forward. Do you mean in your case nothing shown on monitor (I've disabled monitor blanking, so that is not it), sysrq key didn't work, nmi watchdog didn't trigger but you were still able to get output from serial console? An oops? Or, did you use kdb/kgdb in addition to serial console? > If you experience complete hangs it may be something around hanging > interrupts. Probably, yes. > Did you play with apic/acpi etc. to try different interrupt handling? ACPI has never been enabled. I enabled local APIC when I enabled nmi watchdog, so I've tried it on and off. > What does your /proc/interrupts look like compared between 2.2 and 2.4 ? I don't have 2.2 output at hand, but the 2.4.21-jam1 output doesn't seem too suspicious: cat /proc/interrupts CPU0 0: 1675428 XT-PIC timer 1: 3 XT-PIC keyboard 2: 0 XT-PIC cascade 4: 19625 XT-PIC serial 9: 25447 XT-PIC aic7xxx 11: 25203 XT-PIC eth0 12: 0 XT-PIC PS/2 Mouse 14: 178082 XT-PIC ide0 NMI: 16763 LOC: 1675326 ERR: 0 -- v -- v@iki.fi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
