pci_vpd_truncate() should check for dev->vpd->attr, otherwise this might happen: sky2 driver version 1.22 Unable to handle kernel paging request for data at address 0x0000000c Faulting instruction address: 0xc01836fc Oops: Kernel access of bad area, sig: 11 [#1] [...] NIP [c01836fc] pci_vpd_truncate+0x38/0x40 LR [c029be18] sky2_probe+0x14c/0x518 Call Trace: [ef82bde0] [c029bda4] sky2_probe+0xd8/0x518 (unreliable) [ef82be20] [c018a11c] local_pci_probe+0x24/0x34 [ef82be30] [c018a14c] pci_call_probe+0x20/0x30 [ef82be50] [c018a330] __pci_device_probe+0x64/0x78 [ef82be60] [c018a44c] pci_device_probe+0x30/0x58 [ef82be80] [c01aa270] really_probe+0x78/0x1a0 [ef82bea0] [c01aa460] __driver_attach+0xa4/0xa8 [ef82bec0] [c01a96ac] bus_for_each_dev+0x60/0x9c [ef82bef0] [c01aa0b4] driver_attach+0x24/0x34 [ef82bf00] [c01a9e08] bus_add_driver+0x12c/0x1cc [ef82bf20] [c01aa87c] driver_register+0x6c/0x110 [ef82bf30] [c018a770] __pci_register_driver+0x4c/0x9c [ef82bf50] [c03782c8] sky2_init_module+0x30/0x40 [ef82bf60] [c0001dbc] do_one_initcall+0x34/0x1a0 [ef82bfd0] [c0362240] do_initcalls+0x38/0x58 This happens with CONFIG_SKY2=y, and "ip=on" kernel command line, so pci_vpd_truncate() is called before late_initcall(pci_sysfs_init), therefore ->attr isn't yet initialized.
