Subject: [dpdk-stable] ugb_uio: r3.8xlarge bind failure
Date: Thu, 09 Nov 2017 19:20:56 +0200 [thread overview]
Message-ID: <1866566.0zvbrY6xpu@polaris> (raw)

Hello,
There are some AWS R3.8XLARGE instances
that fail to bind Intel 10G VFs with igb_uio [c05cb4f939082].
System dmeg log show this backtrace:
igb_uio: probe of 0000:00:05.0 failed with error -16
IRQ handler type mismatch for IRQ 0
current handler: timer
Pid: 3619, comm: bash Not tainted 2.6.32-642.15.1.el6.x86_64 #1

The VFs can be returned back to kernel ixgbevf driver with no faults.
The instances can bind VFs with igb_uio[b58eedfc7dd57]
I could not find yet why some R3.8XLARGE instances can bind IXGBE VFs with
igb_uio while other fail
