hi, DBDC is available now.
welcome to try it.
Hi all!
Recently I got a new mt7915 dbdc version. Now after installing and testing I got (twice) an issue with it.
It stops working randomly with the next dmesg message:
mt7915_2x2.txt (4.3 КБ)
Not sure if it’s important but both times the problem was started with:
sched: RT throttling activated
P.S. I realize that it might be a HW problem, but may be someone already have faced it.

Can you share your config (hostapd,maybe kernel)?
I guess more it’s a driver issue,which kernel version do you use?

r2-gentoo ~ # uname -r
5.12.0-bpi-r2-hnat
hostapd.conf:
hostapd_2.4G.txt (304 Байта)
hostapd_5G.txt (1.8 КБ)
The kernel conf is defconfig based with some network-related features enabled.
There is a version that reason is insufficient power. Likely I can measure a voltage on wifi load.

I got information,that mt7915 needs 3v3/3a in peak to work stable. But idk if r2 can give this current to pcie. @sinovoip can you tell us whats the max current on 3v3 for bpi-r2 pcie?

At this point, after disconnecting 1 of 2 of my HDDs, I don’t have this issue anymore. I didn’t measure the voltage.
7 days of uptime and active wifi using.

So it looks like a power issue (or maybe interference)

Just a small update (and some questions)
I had some eventual wifi card failures (the same as the top msg), but after instaling a fan all wifi problems are gone(>1.5 monthes of uptime).
So the questions are:
Is it possible to monitor the card temperature?
what is the upper temperature limit?
Thank You!
