Problem with intel wifi driver

[mkryss]

I've recently installed Gentoo and I'm having some problems with my Intel AX201 network card.
At first I was using the experimental kernel patches and noticed that iwd was segfaulting so I checked ip a, and the wlan interface wasn't showing. lspci still showed the device and it showed the iwlwifi driver being used.
I tried removing the experimental patches and got a kernel oops along with some errors in dmesg, with iwd that still kept segfaulting and the wlan interface not showing.
As far as I can tell, it's not a problem with the kernel config, since the same config works on another gentoo install.

Dmesg with experimental patches (nothing weird, as far as I can tell)
Dmesg without experimental patches

Anyone has any idea?

This is likely a bad RAM module as that OOPS is a General Protection Fault in the dmesg

Bad RAM causes strange things to happen in various programs

To add to what grknight mentioned, you can use memtest86(+?) to verify the memory issue. Running it "overnight" up to a day is a good idea. The more memory you have, the longer it takes to test. It is recommended to test from a boot image rather than the installed OS itself.

I ran memtest86+ overnight to check the ram and got 5 passes without any errors, so it wasn't a memory error.

I tinkered with it some more and tried doing a full system upgrade, that included both a kernel and an iwd update. I don't know which one worked but that fixed it and now it works.

Thanks for the help.

Can you explain what tinkering means? If it was only recompiling, then that may be a false sense of resolution.
