Yes ! I've dealt with complex issues that turned out to be vendor-swapped-hardware-woopsie which we spent over a month trying to solve in software before finally figuring it out.

Part of it was difficulty of pinpointing the actual issue - fullness of drive vs throughput of writes.

A lot of it was unfortunately organizational politics such that the system spanned two teams with different reporting lines that didn't cooperate well / had poor testing practices.

The hardest bugs in my experience are those where your only source of vital information is a third party who is straight-up lying to you.

Sometimes it isn't outright lying. I have had the issues with hardware, API and SDK documentation being subtly different from the product as shipped. With hardware with a mixture of revisions, some conforming to doco and other differing and even their engineers not being clear about which is which.
