HPMC Chassis Codes = 2cbf0 2500b 2cbf2 2cbfc Looking at: ftp://ftp.parisc-linux.org/docs/platforms/A2375-90004.pdf CBF0 HPMC handling initiated. CBF2 Invalid length for OS HPMC handler CBFC Branch to OS HPMC failed Just means the linux HPMC handler didn't get called. Hrm. This worked once upon a time and I thought got fixed 6-8 months ago. Next thing I look at is: RUN_ADDR = 0xc1bff0fffed08040 So whatever is at 0xfffed08040 (40 bit addresses physically) was the either the victim or the culprit. Often this is a MMIO BAR plus some offset (probably 0x40). I suggest looking in the Controller driver for that offset and where it's used in the initialization System Responder Path = 0x00ffffff0a010400 This is supposed to match the HPA (Host Phys Address) of one of the devices that is listed at the beginning of the parisc-linux boot. I'm not sure it' accurate though. And then the last part of the PIM that's interesting basically confirms what we have been guessing: '9000/785 B,C,J Workstation HPMC PIM Analysis (per-CPU)', rev 0, 1304 bytes: A Data I/O Fetch Timeout occurred while CPU 0 was requesting information from a device at the path 10/1/4/0 (PCI slot 4). I forgot how to check if the "I/O Fetch Timeout" occurred because the IOMMU already went "fatal" (DMA was attempted to an unmapped address).
