Subject: Help interpreting AHCI failure messages
Date: Fri, 12 Dec 2008 13:23:29 -0800 [thread overview]
Message-ID: <4942D651.1050306@goop.org> (raw)
Hi,
I'm trying to bring up the AHCI driver on a Xen dom0 kernel. There's
almost certainly some problem with my DMA handling somewhere - or
perhaps interrupt routing - which is causing the AHCI driver to fail thus:
xen_set_ioapic_routing: irq 31 gsi 18 vector 184 ioapic 0 pin 18
triggering 0 polarity 1ahci 0000:00:1f.2: PCI INT C -> GSI 18 (level, low) -> IRQ 31
xen: PCI device 0000:00:1f.2 pin 3 -> irq 31

I'm wondering if you can give me a clue as to what might be failing on
the AHCI side to give these symptoms, so I have some idea where I need
to fix things in my code?
Thanks,
J
