Latest working kernel version: never Earliest failing kernel version: always Distribution: Debian Hardware Environment: Two "FireWire (IEEE 1394): Texas Instruments TSB43AB23 IEEE-1394a-2000 Controller (PHY/Link)" devices in one box, with on-board device ill... Software Environment: New FW stack Problem Description: When Vista boots on the hardware, it does something bad to the on-board firewire adapter, so it starts failing to enable card: firewire_ohci 0000:01:09.0: PCI INT A -> Link[APC4] -> GSI 19 (level, low) -> IRQ 19 firewire_ohci 0000:01:09.0: setting latency timer to 64 firewire_ohci: failed to set phy reg bits. firewire_ohci 0000:01:09.0: PCI INT A disabled firewire_ohci: probe of 0000:01:09.0 failed with error -5 When that happens, fw_add_card adds card to the list of all devices, but then returns an error. Caller then thinks that things went wrong, and releases card structure. Then when fw_add_card is invoked for second device, kernel reports linked list corruption, as first (released) card is still in the list... Steps to reproduce: Get box with one broken and one working card, and try loading firewire-ohci module.
