AMD confirms Radeon driver bug causing excessive SSD writes

AMD has confirmed an issue in Radeon drivers Adrenalin 26.10.1 and Adrenalin 26.10.2 that causes excessive SSD writes, generating dozens of gigabytes of unnecessary data. The apparent source is AMD’s External Events Client Module, which runs as atieclxx.exe on Windows and is keeping some users’ system drives constantly busy.

Reported write rates range from 0.3 MB/s to 1.5 MB/s, with one Reddit user reporting sustained activity at 5 MB/s. The affected process belongs to AMD’s External Events Utility, which handles functions including monitor detection and Radeon software hotkeys. It has entered an infinite loop of data writing.

The repeated writes can accumulate during extended system use, creating unnecessary SSD wear and potentially shortening drive lifespan. AMD plans to address the problem with Adrenalin 26.11.1.
