Hi all!
My internet was very slow and I saw the following in dmesg:
[Apr19 10:50] iwlwifi 0000:02:00.0: Queue 10 is active on fifo 1 and stuck for 10000 ms. SW [40, 93] HW [40, 93] FH TRB=0x0c010a037
[ +0,001244] iwlwifi 0000:02:00.0: Microcode SW error detected. Restarting 0x2000000.
The rest of the message is at the end of this message.
The kernel version is "Linux Limone 5.12.0-051200rc7-lowlatency" from https://kernel.ubuntu.com/~kernel-ppa/mainline.
The relevant output of lspci is:
02:00.0 Network controller: Intel Corporation Wireless 7260 (rev 73)
I would be glad to provide additional details if somebody is interested
to fix this bug.
Regards,
Andreas

Do you use MFP?
Could be related to
https://patchwork.kernel.org/project/linux-wireless/patch/20210416134702.ef8486a64293.If0a9025b39c71bb91b11dd6ac45547aba682df34@changeid/
I saw similar issues internally without that fix.

I don't think so. I'm running unmodified kernels from Ubuntu PPA and
don't meddle with WIFI configs.
How can I find out?

A quick "git grep" didn't show any of these two patches in the 5.12-rc7 kernel.

Yeah, my bad, I only put the offending patch into -next, I
misremembered. Sorry for the noise.
