Subject: PROBLEM: do_IRQ: [number] No irq handler for vector (irq -1) [resend]
I repeatedly get "No irq handler for vector" since upgrading to 3.12. I
have confirmed it happens in git master as of yesterday morning
(061f49ec2d722f485237870f04544d8bec15a778). Fixed by disabling VT-d quirk.
[please cc me on responses; I'm not subscribed to the list. Adding
linux-kernel because the iommu list seems broken.]
DETAILS:
This is on a ASUS Sabertooth X58 board. Ever since upgrading to 3.12,
I've been flooded with messages like:
Jan 5 19:06:46 Zia kernel: [292039.181501] do_IRQ: 1.76 No irq handler
for vector (irq -1)
Jan 5 19:08:26 Zia kernel: [292138.390433] do_IRQ: 2.140 No irq handler
for vector (irq -1)
Jan 5 19:40:16 Zia kernel: [294049.535992] do_IRQ: 1.84 No irq handler
for vector (irq -1)
Jan 5 23:12:18 Zia kernel: [306774.882154] do_IRQ: 1.227 No irq handler
for vector (irq -1)
When first booting 3.12, I got the "This system BIOS has enabled
interrupt remapping on a chipset that contains an erratum making that
feature unstable. To maintain system stability interrupt remapping is
being disabled. Please contact your BIOS vendor for an update" message.
I believe I also got the do_IRQ messages in that configuration, but am
not completely sure.
After seeing that, I rebooted the machine and turned off VT-d in the
BIOS. The warning went away after that. However, the do_IRQ messages are
definitely present in that configuration.
I have found one configuration that stops them. I turned back on VT-d in
the BIOS, and then disabled the fix
"iommu/vt-d: add quirk for broken interrupt remapping on 55XX chipsets"
(03bbcb2e7e292838bb0244f5a7816d194c911d62).
Also, I am running BIOS version 1402 (the latest), released 2012-08-29,
with the release notes "improve VT-d compatibility issue." The machine
has been perfectly stable, running pre-3.12 kernels with VT-d enabled
(though I'm not sure I'm actually really using that feature, as I
sometimes use KVM, but don't redirect any real hardware to the VMs).
Here is the patch I used to disable the quirk:
