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 [[Apr19 10:50] iwlwifi 0000:02:00.0: Queue 10 is active on fifo 1 and stuck for 10000 ms.
