Re: [Intel-wired-lan] igc: 5.10.146 Kernel BUG at 0xffffffff813ce19f

From: Kyle Sanderson
Date: Tue Dec 27 2022 - 23:51:43 EST

hi Intel IGC Maintainers,

I've managed to reproduce this issue on 5.15.85 (same steps to
reproduce), and have symbols and line numbers in the below panic.
There's no device support in 5.4 for this hardware, so I was unable to
reproduce the issue there in igc.

>From the Kernel BUG_ON, it's being asked to read beyond the array
size. The min call looks very suspicious (igb, and other drives don't
appear to do that), but I don't know if that's where the issue is.

Please let me know if there's anything more I can do to help.
