Looks like some driver tried to access I/O port 0x2e without checking whether there was possibly anything there first. > Faulting instruction address: 0xc00000000074ded8 > cpu 0x0: Vector: 300 (Data Access) at [c00000003e073aa0] > pc: c00000000074ded8: .f71805f_find+0x44/0x32c > lr: c00000000074e1f8: .f71805f_init+0x38/0x194 > sp: c00000003e073d20 > msr: 8000000000009032 > dar: d00008000000002e > dsisr: 42000000 > current = 0xc0000000220851c0 > paca = 0xc0000000007c2700 > pid = 1, comm = swapper > enter ? for help > [c00000003e073dc0] c00000000074e1f8 .f71805f_init+0x38/0x194 Looks like it might be the f71805f driver, whatever that is... Hmmm, drivers/hwmon/f71805f.c looks like it, and indeed it does go poking around in PCI I/O space with no checks whatever. I suggest you turn off CONFIG_SENSORS_F71805F. It doesn't help, of course, that CONFIG_HWMON defaults to y. :( Paul. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
