What is a tainted Linux kernel? - Unix Linux Stack Exchange To check the kernel tainted state in kernel logs: journalctl -k | grep taint To check the kernel tainted state at runtime: cat proc sys kernel tainted if 0 then kernel is not tainted, else it is The returned value is a bit field; you can find the bit meanings in this table In a kernel panic message, look for a line starting with ‘CPU:’
How to determine which module taints the kernel? My kernel keeps panicking when connected to a certain wireless network I'd like to send a bug report but my kernel is apparently tainted From var log messages: Apr 17 21:28:22 Eiger kernel: [
Are there any real downsides to running a tainted kernel? trace events and enums aren’t set up for tainted kernel modules where the taint could result in incorrect trace data; if a module is tainted for reasons other than being out-of-tree, staging, or unsigned, its state could be invalid and tracing it might cause more problems (think for example of modules which are force-inserted in spite of an
How can I un-taint my DKIM config after exim upgrade? This will still be tainted Force it to lowercase ${lc: } Just 'cos Still tainted; Look up the lowercased tainted domain using lsearch in the tags file Here I use the ret=key option, which means that the returned value from the lookup will be "replaced with a non-tainted version of the lookup key"
Random system freeze, vmware tainted modules - linux A kernel problem occurred, but your kernel has been tainted (flags:GDOE) Explanation: D - Kernel has oopsed before O - Out-of-tree module has been loaded E - Unsigned module has been loaded Kernel maintainers are unable to diagnose tainted reports Tainted modules: vmnet,vmmon Modules seem to be VMware related
Unable to Get Kernel Crash Dump on Kernel Panic The serial console freezes with standard kernel panic stacktrace One of the logs specific to Kdump is: [14645 1099571] CPU: 2 PID: 20518 Comm: tee Kdump: loaded Not tainted 4 19 35-g9e41bb234b42 #2 The system however does not reboot One thing to note is that I can boot into the crash kernel if I want to explicitly:
lsmod outputs: Not tainted - Unix Linux Stack Exchange A running instance of the Linux kernel becomes “tainted” when something dodgy happens The kernel boots in non-tainted state, and becomes tainted if one such dodgy thing happens The full list of dodgy events is documented in sysctl kernel txt, and the kernel's current taint state can be read from proc sys kernel tainted (0 means not tainted)
