iwlwifi: Microcode SW error

[Gon Solo]

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
