XPS13 - 9310 - ath11k with kernel 5.16.2 still needs "treatments"

triplem · 2022-01-24 10:26:57

On the Installer-ISO the wifi comes up fine for the Dell XPS13 9310. After installation of the system, the wifi is not coming up with something like

[7.004154] ath11k_pci 0000:6c:00.0: firmware crashed: MHI_CB_SYS_ERROR

The solution for me was, to add

memmap=12M!20M

to the kernel parameters. I just found out after quite some reading, even though this is also stated in the wiki. But in the wiki it also states, that the wifi-system should work fine with kernels greater then 5.14.

Would be more then happy to know, why it is working on the ISO without any trouble, but on the installed system only after modifications. Have I done anything wrong?

Hi, I am using the XPS 9310 too, do you have the 32gb model with the AX500? I find it very strange that I can't get the Bluetooth working on any arch-based distro no matter the kernel version (works fine on Pop OS or Ubuntu). If you do have that version working would you mind sharing the arch distro, kernel version, linux-firmware version, system firmware version?

Thanks

Hm, I guess, I do own the same machine and do have the same trouble. Me is using a vanilla Arch Installation with the latest versions of kernel (5.16.2) and the corresponding firmwares. Is wifi working for you with the vanilla installation? Have you had to modify the kernel parameters?

There was a thread [1] recently with weird memory issues due to CSM compat bugs in Dell's UEFI/BIOS. Make sure that CSM emulation is disabled if you don't have an actual need for a legacy/non UEFI boot (... and if you actually have a BIOS boot, try setting up proper UEFI instead)

I did not try vanilla arch so I can't comment. So far my experience with archcraft and axyl is that wifi works just fine with the latest kernel (both on the live iso and on the installation). BT on the other hand is not working at all, does it work for you?

Hm, guess, that this is a different problem and it is not showing on my machine.

How Bad, and no, BT is not working for me either.

I know you are not seeing this particular problem but the question is whether you have CSM enabled/do a legacy boot in which case you should try and disable that. Funky memory mapping sounds like potentially related to this.

triplem · 2022-01-24 22:02:13

Guess that CSM is not available anymore on modern systems, since windows 7 was the last version where this kinda mode was necessary.
Anyways the ISO does start correctly as well...

Hm....

Working WIFI and BT now?

No, unfortunatly BT is not working, but this seems to be an issue in the kernel and should be fixed with the 5.17 release. But this is just a guess.

Thanks for reporting back, I don't it is related though. BT doesn't work with previous versions of the kernel either. Hopefully, you are right.
