Other Software

In Ubuntu 24.04, I've installed linux-tools-generic, which installed linux-tools-6.8.0-110, allowing me to run perf, and, in particular perf stat.

Unfortunately, the longer I run perf stat on a CPU intensive program, the higher the chance it's going to kill my Linux environment, printing this message in the terminal (pardon my french):

[processus terminé avec le code 1 (0x00000001)]
Vous pouvez maintenant fermer ce terminal avec CTRL+D, ou appuyez sur Entrée pour redémarrer

My traduction:

[process exited with code 1 (0x00000001)]
You could now close this terminal with CTRL+D, or press Enter to restart

Looking at the files in C:\Users\<username>\AppData\Local\Temp\wsl-crashes, I see the same call trace every time my session is interrupted by a crash:

Repro Steps

sudo apt install linux-tools-6.8.0-110-generic
/usr/lib/linux-tools/6.8.0-110-generic/perf stat <a command burning CPU cycles for minutes>

Expected Behavior

The Linux kernel should not panic, and perf stat should complete.

Actual Behavior

The Linux kernel encounter a fatal exception and panic, killing the running Ubuntu distribution and my perf stat command.
