Bug#1123591: reportbug: Kernel 6.17.11 "ixgbe"-driver broken (OEM Intel X540-AT2 card)

Hi, Bastian !

Thanks for your swift reply, appreciated.

Well, I have been using this Intel-card for several years now (I think at least 2 years),

going through Deb 12 / 13 / even Sid and never got any issues. I think it broke yesterday,

when I updated my Forky and kernel 6.17.11 got in. At first, I wondered if it was my router or switch that needed a reboot :)

To confirm, I don't find this being a hardware fault, since the card continues working under Win11 (from which I am now writing to you).

Debian's boot goes normal, the ixgbe-driver load succeeds and the desktop gets fully loaded (Plasma 6).

I was at something, when I suddenly got network issues - browser stopped loading, or was it Steam ?

Anyway, it was exactly then, when I fired up dmesg and saw these lines :

"Adapter removed

Warning firmware error detected FWSM: some hex"

I need to reboot my machine, boot Deb with this NIC again, so that I provide you with the exact dmesg-messages.

Please, tell me what log(s) you need to collect, since I generally do not configure logging and rarely look at logs, thanks !

Cheers,

Radi

Please provide some information. What is broken. How is it broken.
Since when is it broken. And the complete kernel log.

ipv6.disable=1 is unsupported.

You have proprietary modules loaded. Does it also fail without?

Okay, the error counters are pretty high.
