2.4.3-2.14.19 i686 I've run this in 3 i686 systems, pretty much alike all. One has given an oops. I have no idea why; no heavy use or anything. Will see if this repeats. This happened at 04:24:15 in the sat-sun morning, when there was zero use by me (idle ssh connections, X was sitting in xlock). Perhaps a cron.weekly job gone awry. Only cron.weekly jobs are 0anacron, logwatch and makewhatis. Now typing over ssh is very sluggish, will reboot. # more /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 3 model name : Pentium II (Klamath) stepping : 3 cpu MHz : 267.275 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov mmx bogomips : 532.48 # more /proc/interrupts CPU0 0: 5933062 XT-PIC timer 1: 11034 XT-PIC keyboard 2: 0 XT-PIC cascade 4: 1 XT-PIC serial 8: 1 XT-PIC rtc 9: 1530358 XT-PIC mga@PCI:1:0:0 10: 188744 XT-PIC eth0 11: 0 XT-PIC usb-uhci 12: 16013 XT-PIC PS/2 Mouse 14: 20576 XT-PIC ide0 15: 0 XT-PIC ide1 NMI: 0 LOC: 10012095 ERR: 26 MIS: 0 # lsmod Module Size Used by nls_iso8859-1 2880 1 (autoclean) nls_cp437 4400 1 (autoclean) vfat 8944 1 (autoclean) fat 30272 0 (autoclean) [vfat] loop 8336 2 (autoclean) mga 84304 2 agpgart 22016 3 epic100 10864 1 (autoclean) usb-uhci 20224 0 (unused) usbcore 48352 1 [usb-uhci] # lspci 00:00.0 Host bridge: Intel Corporation 440LX/EX - 82443LX/EX Host bridge (rev 03) 00:01.0 PCI bridge: Intel Corporation 440LX/EX - 82443LX/EX AGP bridge (rev 03) 00:07.0 ISA bridge: Intel Corporation 82371AB PIIX4 ISA (rev 01) 00:07.1 IDE interface: Intel Corporation 82371AB PIIX4 IDE (rev 01) 00:07.2 USB Controller: Intel Corporation 82371AB PIIX4 USB (rev 01) 00:07.3 Bridge: Intel Corporation 82371AB PIIX4 ACPI (rev 01) 00:0a.0 Ethernet controller: Standard Microsystems Corp [SMC] 83C170QF (rev 06) 01:00.0 VGA compatible controller: Matrox Graphics, Inc.

This hasn't happened again so far.
strange..... I'm closing this as "worksforsome", if it happens again please reopen.
Ok, this happened again on the same system with 2.4.3-12 kernel. In XFree86, mouse moved but clicking didn't do anything; keyboard wasn't responding. I could SSH in (felt really slow, but no apparent sources of load), kill all processes etc. but rebooting wouldn't help, had to reset the box.

Nope, I don't recall seeing it.. currently running 2.4.18-19.7.x for 135 days.
