How to eliminate error messages "do_IRQ: n.nnn No irq handler for vector (irq -1)"


My employer recently purchased two new L3 Communications 550 Telemetry Front End systems.
The configuration of both systems is believed to be identical.
Each system has an associated HP Z840 computer/workstation running Linux RedHat version 7.3.
On the 1st HP Z840 system, the error messages

"Kernel: do_IRQ n.nnn No irq handler for vector (irq -1)"

occur upon occasion.
These messages have not occurred on the other (2nd) system.
What do these messages indicate and how can they be eliminated?

Thank You,
gwpucci

The message means that there has been an interrupt that has no handling associated. Normally it means either a configuration problem, a bug in the driver or misbehaving hardware. I would start from contacing the technical support if the devices are new and under warranty and you haven't modified the configuration.

If you want to debug it, try to correlate the moment when the message arrives (you can run dmesg -w -H to view the log in real time in a terminal) to a hardware operation. Is it a moment when you plugged something, started some device operation etc.

Still don't know what's causing this situation.
However, it appears to be an annoyance rather than a serious error because after an error occurs the system is still operational and the errors occur infrequently.

Do not rest until it is solved.

The device obviously should not be doing any such thing, and you have no way to be certain which interrupts it might be mis-handling. Therefore, "well, it seems to be working ..." is not sufficient.

Get the hardware vendor involved.

"This is not what your employer is paying good money for." The monkey is upon the vendor's back to make good on his sales contract. (As we must presume that he speedily will do. "This is business, after all, and you're not their first client.") Very-politely hold the vendor's feet to the fire ... ... until the problem is fixed to everyone's mutual satisfaction.

Explicitly and timely notify your management at once that the issue exists. Keep them timely apprised of the resolution process. Advise them very promptly when you consider that the issue is fully resolved, in case they have been withholding full or partial payment.

What was suggested/implied in the last post is being done.
Use of LinuxQuestions.org is being done in parallel to hopefully
help resolve the IRQ error/message issue.
Due to the fact there are other open issues that also need to be resolved,
priorities need to be assigned to resolution of the outstanding issues.
There is no intent on my part to drop this issue until it
is successfully resolved.
