We may need the contents of PFHMC_ERRORINFO and PFHMC_ERRORDATA
registers to figure this out.
I suspect that this may be something to do with interrupts being enabled.
However from reading the code, looks like interrupts should be disabled
by default unless explictly enabled.

Section 7.9.5
HMC related errors are reported through the PFHMC_ERRORINFO (see Section
11.1.2.8.56) and PFHMC_ERRORDATA (see Section 11.1.2.8.57) registers.
The HMC_ERR interrupt status bit in the PFINT_ICR0 register may also
deliver an interrupt for HMC errors if the interrupt is enabled in the
PFINT_ICR0_ENA register. When the HMC detects an error, it sets the
PFHMC_ERRORINFO.ERROR_DETECTED bit along with the relevant information
in the other fields of the PFHMC_ERRORINFO and PFHMC_ERRORDATA
registers. No further notification of subsequent HMC errors associated
with any given PF will be issued until the current error is acknowledged
by writing a 0 to the PFHMC_ERRORINFO.ERROR_DETECTED bit. Table 7-187
describes the errors detected for each HMC object and the behavior
associated with each error.

Guys,
I've updated VPP to vpp.x86_64 0:18.01-rc0~405_g7f0d1d3 and when
I enable a interface, I get this love note:
i40e_dev_interrupt_handler(): ICR0: HMC error
Aborted
This used to work, of course. Some more details below.
Any notions?
Thanks,
