Enabling ACPI clears resources on PCIe bridges: pcib2: <ACPI PCI-PCI bridge> irq 17 at device 28.0 on pci0 pcib2: domain 0 pcib2: secondary bus 2 pcib2: subordinate bus 2 pcib2: I/O decode 0x0-0x0 pcib2: no prefetched decode pcib3: <ACPI PCI-PCI bridge> irq 16 at device 28.1 on pci0 pcib3: domain 0 pcib3: secondary bus 3 pcib3: subordinate bus 3 pcib3: I/O decode 0x0-0x0 pcib3: no prefetched decode pcib4: <ACPI PCI-PCI bridge> irq 18 at device 28.2 on pci0 pcib4: domain 0 pcib4: secondary bus 4 pcib4: subordinate bus 4 pcib4: I/O decode 0x0-0x0 pcib4: no prefetched decode Fixing this require significant improvement of the PCI code, which wasn't done yet. At this moment I am using machine-specific local hack to set proper resources there (same as in non-ACPI mode) by hands: http://people.freebsd.org/~mav/tm6292_pcie.patch -- Alexander Motin _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-mobile To unsubscribe, send any mail to "[email protected]"
