The problem is in the function pci_map_mem() in the file /sys/pci/pci.c. The size of the region to map (psize) is calculated incorrectly. This function uses pci_conf_read() to intialize a variable called data. On a PILA8461 card data is set to 0x7ffff000. Then psize is calculated using the following magic code: #define PCI_MAP_MEMORY_ADDRESS_MASK 0xfffffff0 psize = -(data & PCI_MAP_MEMORY_ADDRESS_MASK); This results in psize receiving a value of 0x80001000. This value of psize when passed to pmap_mapdev() causes a panic. FYI, values from a working PILA8460 card are: data - 0xfffff008 psize - 0x1000 >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
