Again look like these are disabled channels. At least chanspec

is 5G channel 34. You say you get this only once so not every 60
seconds?
I get this everytime i trigger a reconnect to the wifi
network, so
not
periodically (checked that). Strangely the initial automatic
connect
doesn't trigger this errors.
I additionally placed a WARN_ON_ONCE after the error log and
enabled the
firmware error log of brcmf_fil_cmd_data(). Maybe this helps.
It does a bit. At least it shows this is happening with the
dump_survey (again). I don't really understand why though. It
implies
the channel is not disabled, but unclear why. The channel flags are
changed in brcmf_construct_chaninfo() so we probably should focus
debug on that function.
i placed a pr_err at the start of brcmf_construct_chaninfo and
another
pr_err into the for loop before the "if (channel->orig_flags &
IEEE80211_CHAN_DISABLED) continue".
pr_err("%s: Ch num %d, chanspec 0x%x, orig_flags: %x.\n", __func__,
ch.control_ch_num, ch.chspec, channel->orig_flags);
It seems that brcmf_construct_chaninfo is called two times, but the
results are different. I could find 0xd090 in the first run, but
not in
second. The other chanspecs doesn't seem to occur in both runs. No
idea
what's going on here.
Can you print all wiphy band channels before exiting
brcmf_construct_chaninfo() and print both channel->orig_flags and
channel->flags?
Sure. It seems that in the first call of brcmf_construct_chaninfo the
channel 144 is not disabled, but in the second.
I am a bit confused. So the chanspec as mentioned in this email
subject is no longer observed, but you still see failure in
brcmf_set_channel() for other chanspecs?
before we dive deeper into this let me summarize my observations from
the beginning. From my understanding the errors are triggered for the 5
GHz channels 34, 38, 42, 46, 144 (chanspec: 0xd022, 0xd026, 0xd02a,
0xd090). So i would focus my observations on those.
As you said that the channel flags are set in brcmf_construct_chaninfo()
i dump them, here is the output of the first call:
[ 8.785850] brcmfmac: 5 GHz: 0: hw_value 34: orig_flags: 00080000,
flags 00000001
[ 8.785861] brcmfmac: 5 GHz: 2: hw_value 38: orig_flags: 00080000,
flags 00000001
[ 8.785872] brcmfmac: 5 GHz: 4: hw_value 42: orig_flags: 00080000,
flags 00000001
[ 8.785882] brcmfmac: 5 GHz: 6: hw_value 46: orig_flags: 00080000,
flags 00000001
[ 8.785974] brcmfmac: 5 GHz: 23: hw_value 144: orig_flags: 00080000,
flags 0000011a
All of them except 144 are disabled via flags. Btw wpa_supplicant is
configured to country DE within the configuration.
The second and last time brcmf_construct_chaninfo() is called is a few
seconds later during boot, we get the following:
[ 12.490877] brcmfmac: 5 GHz: 0: hw_value 34: orig_flags: 00080000,
flags 00000001
[ 12.490891] brcmfmac: 5 GHz: 2: hw_value 38: orig_flags: 00080000,
flags 00000001
[ 12.490904] brcmfmac: 5 GHz: 4: hw_value 42: orig_flags: 00080000,
flags 00000001
[ 12.490918] brcmfmac: 5 GHz: 6: hw_value 46: orig_flags: 00080000,
flags 00000001
[ 12.491031] brcmfmac: 5 GHz: 23: hw_value 144: orig_flags: 00080000,
flags 00000001
Now all of them are disabled via flags.
So after that i trigger the reconnect to the same 5 GHz network as
before. brcmf_construct_chaninfo is never called again, but at the time
brcmf_set_channel is called the flags for these channels are completely
different:

Where does these new flags come from? It's clear that these doesn't come
from brcmf_construct_chaninfo(). So what manipulates the flags
afterwards? Shouldn't brcmf_construct_chaninfo() called on reconnect?
I suspect it is not the driver, but net/wireless/reg.c. Could you
define DEBUG in top of that file and build cfg80211.ko with that. Or
if you have CONFIG_DYNAMIC_DEBUG enable debug prints for reg.c through
sysfs [1]
Sure, this is a more recent Linux 6.7 and the disconnect is at uptime
~316s followed by the reconnect:
