Affected Product(s):
BIG-IP LTM
Known Affected Versions:
11.4.0, 11.4.1
Fixed In:
11.4.1 HF2, 11.4.0 HF4
Opened: Aug 20, 2013 Severity: 2-Critical
On platforms with the ngfips controller which have interrupt remap hardware, interrupts from the ngfips controller use the wrong pci source path [bus:slot:function] which is trapped by the interrupt remap hardware. This was causing 2 problems: (1) The interrupt was trapped (and ignored) causing the following output from the kernel. DRHD: handling fault status reg 2 INTR-REMAP: Request device [[03:00.1] fault index 25 INTR-REMAP:[fault reason 38] Blocked an interrupt request due to source-id verification failure (2) More importantly the ngfips driver was never seeing the interrupt from the controller.
Interrupt remap filters are not handled properly, and errors are logged.
Happens during the loading of the ngfips driver.
None.
The interrupt remap filtering are properly delivered to the ngfips driver.
