AMD Radeon R5 230 (TeraScale 2) locks up with frequent window size changes
With an AMD Radeon R5 230, whilst using KDE (browsing the web, using the terminal), the desktop interface would freeze occasionally, then goes to a blank screen, recovering in about 10 seconds, with the cursor still working but not responding to any clicking. The interface would not recover itself.
Key component versions are as follows:
- Linux Kernel 6.11-rc6 (also observable on 6.6 and 6.10)
- Mesa 24.2.1
- xf86-video-ati 22.0.0 (also observable with modesettings)
While investigating this issue, I have came up with the following reproducer:
- Open Firefox and Thunderbird, tiling the two windows side-by-side.
- Drag to automatically resize both windows, rapidly.
- The interface freezes in about 5 - 10 seconds.
The dmesg at this point indicates that the GPU had reset successfully (and agrees with the 10-second delay between freezing-blanking-recovering:
