Subject: Problems since commit Recognize that Interrupt Line 255 means "not connected"
Date: Sat, 6 Feb 2016 00:00:32 +0100 [thread overview]
Message-ID: <56B52990.3030103@gmail.com> (raw)
Since commit a44c386a361e "x86/PCI/ACPI: Recognize that Interrupt Line 255
means "not connected"" I get several "PCI INT not connected" warnings on
a Zotac CI321 and EHCI failes to load:
ehci-pci 0000:00:1d.0: PCI INT not connected
ehci-pci 0000:00:1d.0: EHCI Host Controller
ehci-pci 0000:00:1d.0: new USB bus registered, assigned bus number 3
ehci-pci 0000:00:1d.0: debug port 2
ehci-pci 0000:00:1d.0: cache line size of 64 is not supported
ehci-pci 0000:00:1d.0: request interrupt -2147483648 failed
ehci-pci 0000:00:1d.0: USB bus 3 deregistered
ehci-pci 0000:00:1d.0: init 0000:00:1d.0 fail, -107
ehci-pci: probe of 0000:00:1d.0 failed with error -107
XHCI brings the "PCI INT not connected" warning too but loads properly
(most likely because it uses a MSI interrupt).
Not sure whether this commit is to blame or a broken BIOS.
Just let me know in case you need additional information.
Regards, Heiner
