(solved) RTW: ERROR [HALMAC][ERR]Dump efuse in suspend

[mlewus]

I built a new kernel for the Raspberry pi 4 then built and installed the 88x2bu-20210702 driver, for a TP-Link USB Wi-Fi adapter I have never used before. It seems to work fine as a wifi interface (no AP mode, no 867 MHz, no concurrent mode, USB2). But I’m getting kernel error messages in /var/log/messages and dmesg when the driver is loaded at boot.

The adapter is a TP-Link Archer 3U Plus, connected to a USB2 hub. I know USB2 is not ideal, but it would be difficult to replace it with a USB3 hub in my existing project. I am connected to a 2.4 GHz AP so throughput should not be an issue.

Thanks in advance for any help you can offer.

——- Config & Requested Info ——- Pi 4, 4GB Ram, Pi OS 10 ‘Buster’ with upgraded kernel 5.10.89.

try rtw_switch_usb_mode=1 in '/etc/modprobe.d/88x2bu.conf'

[mlewus]

I tried that, it just breaks it. It crashes multiple times and gives up, with no wifi interface. Anyone have any other ideas? Or should I just disregard the error messages on startup?

[PieGuy314]

Is the USB hub powered?

[mlewus]

Good question :) The hub is buried inside a magic mirror, and I don't remember if it was a powered hub. I'm really trying to not have to open it up. But I don't think it's a power problem because once it gets started it works fine. I just get the initial two or three crashes at startup, and then it initializes and works after that. Maybe I should just leave well enough alone and forget it.

[PieGuy314]

The errors are consistent with the Wi-Fi adaptor failing during boot. The initial current draw on these adaptors is high. Having an unjuiced hub isn't going to help. The fact that it eventually works suggests a power supply issue.

It's wrong to assume a USB port can power a hub with a load of gadgets hanging off it. Been there; learnt that.

Hi @mlewus

I tried that, it just breaks it. It crashes multiple times and gives up, with no wifi interface.

Ouch. Not a good idea to force USB3 when the adapter is not in a USB3 capable port.

Or should I just disregard the error messages on startup?

This. I did not see any unknown entries and I did not see anything that looked like an operational bug report. Realtek's logging with this driver is not going to win them any prizes. I suggest:

rtw_drv_log_level=0

...and press on. This is actually a pretty good driver for a Realtek out-of-kernel driver but that **** it spews in the log is just noise. I ignore it.

[PieGuy314]

try rtw_switch_usb_mode=1 in '/etc/modprobe.d/88x2bu.conf'

I think I meant to write 'rtw_switch_usb_mode=0'

Apologies.

[mlewus]

i’ll try mode 0 but failing that, as long as it keeps working I’ll just ignore it.

[morrownr]

Hey @PieGuy314

Long time, no see. How is it going? I'm still waiting for you to rewrite the logging code in this driver... he he

[mlewus]

Changing the USB mode from 2 to 0, no effect. But other than startup messages the adapter is reliable, which is way more than I can say for the internal Wi-Fi chip on the pi 4. That one was crashing on a daily basis, requiring me to rmmod/modprobe the driver to get it back up. This is way better. Thanks for all the work will you guys put into this!
