Subject: commit 7ffb791423c7 breaks steam game
Date: Mon, 10 Mar 2025 12:22:04 +0100 [thread overview]
Message-ID: <20250310112206.4168-1-spasswolf@web.de> (raw)
Using linux next-20250307 to play the game stellaris via steam I noticed that
loading the game gets sluggish with the progress bar getting stuck at 100%.
In this situation mouse and keyboard inputs don't work properly anymore.
Switching to a VT and killing stellaris somewhat fixes the situation though in
one instance the touchpad did not work after that. I bisected this between
v6.14-rc5 and next-20250307 and got this as the first bad commit:
7ffb791423c7c518269a9aad35039ef824a40adb is the first bad commit
commit 7ffb791423c7c518269a9aad35039ef824a40adb (HEAD)

x86/kaslr: Reduce KASLR entropy on most x86 systems
Reverting commit 7ffb791423c7 in next-20250307 fixes the issue for me.
The OS is debian sid (last updated 20250309) and this is the hardware
is an MSI Alpha 15 Laptop:
