Hi,
I have solid hangs (no log) with SMP machine for some time. I swapped almost all of the hardware (incl mobo). Dual PIII 677 MHZ on MSI 694D mobo. I had the hangs with 2.2.19 AND now also with 2.4.4. I linked the kdb in the kernel and when the lockup occurred I was able the get some info (serial console).
This is the kdb output for linux-2.4.4
