@jackoneill I've been running with those options in modprobe.d using the built-in kernel module for a few days now and my system hasn't crashed so far. I'll report back if it does

@senorsnor: Those patches do the same thing as putting „options rtw_pci disable_aspm=1” in a file in /etc/modprobe.d/, but only for those specific machines. („rtw88_pci” for the built-in module, and „rtw_pci” for lwfinger's version.)

Have you tried that option? I tried it and it didn't help. My laptop is HP 250 G7.

Recently some patches were done describing the exact same symptoms some of us face:

https://marc.info/?l=linux-wireless&m=162557122731962&w=2 https://marc.info/?l=linux-wireless&m=162507517501401&w=2

Both "disable pci capabilities" based on hardware model: Protempo Ltd L116HTN6SPW and HP Pavilion Laptop 14-ce0xxx respectively. I'm not familiar with C or kernel/driver development so I don't know exactly what this is about, but this solution worries me:

My laptop, which shows the exact same symptoms, is an HP Pavilion Laptop 15-cs0xxx (note the 15-cs, rather than the 14-ce as in the patch).

Before I reply with this to the mailing list, I thought I make an inventory here with the people that run into the same issue. Which hardware are you using?

You can find the info with the command sudo dmidecode | grep -A3 '^System Information'

For me the screen doesn't update either, mouse movements and key presses are not processed anymore. System is completely frozen. Not sure about the fan speed during a system freeze.

When using the kernel drivers, my system feels unstable. Fan speed goes up and down at seemingly random moments. When I tested with rtw88-dkms-git that seemed to have disappeared, unfortunately my system still freezes.

@CodingEagle02: It doesn't look like that here. The screen looks normal, it just doesn't update anymore. The mouse cursor doesn't move. Ctrl+Alt+F1..6 have no effect. The fan may speed up a little after a while. It doesn't go full speed. I didn't try the Sysrq stuff.

What kinds of freezes are you all getting? I've noticed I get a really weird and specific, where my screen suddenly goes black, and my fan starts going at full speed. The kill X server command doesn't work, but REISUB mostly does. I never used to get these. I'm too lazy to post the logs somewhere at the moment, but if people are dealing with the same thing, then I guess it's just a matter of waiting until Linus and Realtek get their shit together.

@jackoneill ok too soon .. system just froze twice with rtw_8821ce

senorsnor commented on 2021-05-21 08:50

@jackoneill Thanks for that, then indeed I tested with the current kernel driver. Now testing rtw88-dkms-git for a few hours and so far it works great. If the system crashes then i'll report here.

jackoneill commented on 2021-05-20 21:19

The driver that comes with the kernel is called rtw88_8821ce (and rtw88_{8821c,pci,core}). The driver in the rtw88-dkms-git package is called rtw_8821ce (and rtw_{8821c,pci,core}). The driver from the kernel seems to have higher priority. So the file in /etc/modprobe.d/ needs to contain these lines:

blacklist rtw88_8821ce blacklist 8821ce

@jackoneill I just installed rtl88-dkms-git, removed rtl8821ce-dkms-git, unblacklisted the rtw88-driver. Rebooted, system froze within an hour. I didn't know how to verify that the driver from the package is used, and not the driver supplied with the kernel? Oh, and the system seemed to use excessive cpu as well, but not sure.
