[Xen-devel] [PATCH 0/3] xen/x86: Improvements to asm assertions

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

In XenServer, we have a single server which occasionally finds interrupts
unexpectedtly in the wrong state (I suspect the SMM handler).  However,
asserts from ASSERT_INTERRUPTS_{EN,DIS}ABLED are quite opaque, being an
unqualified fatal #UD.

  xen/x86: Use real assert frames for ASSERT_INTERRUPTS_{EN,DIS}ABLED
  DO NOT APPLY - test code for this series
