| >= 11 || iwlwifi || WLan || Unstable work with messages in '''dmesg''':
<pre>
[36338.287415] iwlwifi 0000:03:00.0: missed beacons exceeds threshold, but receiving data. Stay connected, Expect bugs.
[36338.287425] iwlwifi 0000:03:00.0: missed_beacons:23, missed_beacons_since_rx:3
</pre>
* fixed by creation a file /etc/modprobe.d/ath9k_htc.conf with the content:
<pre style="margin-left: 20px;">
options ath9k_htc use_dev_fw=1
</pre>

| >=8 || Any || GLibC || Significant degradation of the memory allocation, especially bright represented in [[Special:MyLanguage/Modules/WebVision|the module UI.WebVision]] — [[Special:MyLanguage/Modules/WebVision#Efficiency|the problem analyzing]].
* the problem is a disadvantage of the memory allocation arenas linked to threads, which causes to such sort inter-arenas memory fragmentation on high dynamic using, what recreates the threads. As a workaround there is globally used the environment variable MALLOC_ARENA_MAX=1 to set the arenas number to 1!
| '''FIXED'''
|-
| 10 || Any || KMix || Missing PulseAudio.
* KMix was made dynamic by the patch "[https://bugs.pearsoncomputing.net/show_bug.cgi?id=2782 kmix-UpdMixersForChangeAndChMaster.patch]".
| '''FIXED'''
|-
| >=8 || Any || Plymouth || The console starting splash images locks the first screen of the console and does not stop with "systemd", so /var/boot.log grows indefinitely.
* TDM switched in the SDM mode then plymouth stops now after TDM start.
| '''FIXED'''
|-
| 11,10,9 || RTL8192EU || WLan || [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=914999 The WIFI-adaptor does not connect].
* we need [https://github.com/Mange/rtl8192eu-linux-driver/issues/46 to append] in the file /etc/NetworkManager/NetworkManager.conf for these lines:
<syntaxhighlight lang="INI" style="margin-left: 20px;">
[device]
wifi.scan-rand-mac-address=no
</syntaxhighlight>
| '''FIXED'''
|-
| >=9 || Any || WIFI Hot Spot || [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=919294 Does not work, tested with Nokia N9].
* resolved as a regression or the security level rising in '''wpasupplicant''' of the version 2.4 (or OpenSSL 1.1) — workaround by the downgrading to version 2.3.

| 13,12,10,9 || AMD APU || Radeon || [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=879992 Rebooting just in the Linux kernel boot, detected on AMD A8-6500 APU].
* resolved as a bug of the video driver Radeon in enabling DPM by default. Workarounded by the Linux kernel argument "radeon.dpm=0" and that applied in task-tde-desktop 1.2-7 also for fixing in the installed systems from those Live Disks;
* officially fixed in Linux kernels version 5 and broken again in 6.
