Hello -
We've been seeing intermittent (~weekly) lock-ups with our PCs which never happened with the 2.2.16 kernel. Today the console on one of them froze shortly after booting up to the text login (no X). But this particular time, it still accepts ssh connections, so is there anything I should check while it is in this state? /proc/interrupts shows one very interesting thing:
CPU0 0: 63444 IO-APIC-edge timer <-- Not incrementing anymore! 1: 2 IO-APIC-edge keyboard 2: 0 XT-PIC cascade 8: 0 IO-APIC-edge rtc 12: 245 IO-APIC-edge PS/2 Mouse 13: 1 XT-PIC fpu 14: 858 IO-APIC-edge ide0 15: 7 IO-APIC-edge ide1 19: 110413 IO-APIC-level usb-uhci, eth0 NMI: 0 ERR: 0
Mouse and keyboard interrupts are also not incrementing, but the disk and network interrupts are. The kernel seems happy (no errors logged.)
Linux version 2.2.20-smp #1 SMP Sun Mar 24 18:35:47 HST 2002 Built with: gcc 2.7.2.3, binutils 2.11.90.0.8 Patches: Vanilla tree plus DEVFS and RAID 0.90 Machine: Dell Precision 210 Workstation Motherboard: Dell, 440BX based (supports dual processors) Processor: Single P-III 500 MHz PCI Cards: Only an NVidia graphics card (but X was never started yet.) Memory: 1GB ECC Disks: 2x13GB Maxtor IDE's on hda,hdb
The same thing happened before with a 2.4 kernel a few months ago. At that time the machine had 512MB of RAM. If anything useful can be done to track down the problem while the machine is like this, please let me know and I'll try before rebooting tomorrow.
Thanks,
