This issue occurs in the 5.12.x branch. Doesn't occur in kernal version 5.11.16. Browsing through images in gwenview shortly freezes gwenview. The same occurs when running a game on Steam. The respective processes enter disk sleep (i.e. kworker, wineserver, file.so, thumbnail.so, or gwenview). The computer requires a hard reset to reboot. The files are stored on a HDD+SSD bcache.

Behavior with Gwenview occurred on a custom kernel with the OpenRGB patch and the following config options enabled for an android emulator: CONFIG_ASHMEM=y CONFIG_ANDROID=y CONFIG_ANDROID_BINDER_IPC=y CONFIG_ANDROID_BINDERFS=y CONFIG_ANDROID_BINDER_DEVICES="binder,hwbinder,vndbinder" After shifting through 5-10 images in Gwenview, Gwenview entered disk sleep. Gwenview behaves correctly on the stock kernel. The bug still occurs when launching a game on Steam Steam displays a dialog box with the text: Preparing to launch [GAME NAME] The game never launches. Tested with Disgaea PC, NieR:Automata, and Middle-earth: Shadow of War with the same result. Each game launch produces the same journal entry above with the same behavior. Installing a game to the boot SSD launches the game correctly bcache_writebac enters disk sleep as well. Editing documents and deleting files works before the bug occurs. After a process has entered disk sleep, files can sometimes be viewed but saving changes does not work. Deleting files on the bcache drive also does not work after the bug occurs.
