[Kernel-packages] [Bug 1764892] Re: e1000e msix interrupts broken in linux-image-4.15.0-15-generic

[Zheng Cui]

Hi,

Our team has verified Ubuntu 18.04 + "proposed" solve the problem and as
far as I am concerned, we could mark the tag as "verification-done-
bionic":



Thanks,

  e1000e msix interrupts broken in linux-image-4.15.0-15-generic

Status in linux package in Ubuntu:

Status in linux source package in Bionic:
  Fix Committed

Bug description:
  == SRU Justification ==
  Linux kernel 4.15 has introduced a bug in e1000e msix interrupt drivers,
  which violates the e1000e specification. Specifically, the driver
  configures auto-clearing of the "OTHER" interrupt types, and the "OTHER" 
interrupt
   handler expects to see an uncleared interrupt source for the "OTHER" types;
   consequently, the link state change interrupts are not identified by the 
driver,
   and thus the virtual E1000e device doesn't function correctly inside VMware 
VMs.

  This patch Fixes: 4aea7a5c5e94 ("e1000e: Avoid receiver overrun
  interrupt bursts")

  == Fix ==
  745d0bd3af99 ("e1000e: Remove Other from EIAC")

  == Regression Potential ==
  Low.  Fixes an existing regression and limited to e1000e driver.

  == Test Case ==
  A test kernel was built with this patch and tested by the original bug 
reporter.
  The bug reporter states the test kernel resolved the bug.

  I have verified that Linux kernel 4.16.2 has fixed the issues and our
  on-perm QE has verified 4.16-RC functions correctly inside VMware VMs.

  Could you please crossport the fix from linux-4.16 into Ubuntu 18.04
  that would be frozen in 2 days? Here are the change history:

I have been posting the verification request to our QE team, and would
update here once I heard of anything.

Hi Joseph,

Would update #5 be sufficient for the verification? If so, we should be
able to update the tag to verification-done-bionic. Otherwise, let me
know what we should do next.

Thanks,
