Re: ixl(4) troubles

Leaving a headstone for the next person who goes looking:

It was the transceivers. Some intel-coded transceivers from FS worked

straight away.

Thanks all who provided helpful suggestions and pointers, I appreciate

it.

hi Matthew,

We are using multiple ixl(4) quad cards and encountered the same issue when testing with 3rd party optics.

Using official intel optics or re-branded optics works ok for us on openbsd 7.4.

Kind regards,

Thanks, Jan & Stuart -- I'll grab some more likely intel compatible transceivers and give them a shot.

I appreciate the pointers.
