This particular system crashes after about 12 hours. I have tried the vm_page.c patch among other things. I also get Panics related to a page fault in kernel mode. They always occur when reading from dual-port memory mapped through a PCI-ISA bridge to an ISA sync card. A kernel trace back of the core dump always points to this. It is an 200 Mhz AMD processor of the latest stepping and uses the TX chipset and 82371AB (PIIX4) PCI-ISA bridge (which BTW is identified as generic bridge by the pci_support.c procedures). To make matters even more interesting, I am running the new experimental Harp2.1 ATM code (with the latest patches) and an Efficient OC3 PCI card, one of Dennis's ET5025-16 ISA sync cards, two PCI, Intel fxp type cards, and Trident video on ISA. It has been suggested to me that I am having an ISA bus failure of some type. Can anyone comment on this configuration/situation?
