--- Comment #5 from Alan W. Irwin Alan.W.Irwin1234@gmail.com --- Hi Michel: Since the lock ups occurred during ordinary (KDE) desktop use when I wasn't running 3D games I ignored mesa upgrades and instead concentrated first on trying a new kernel version (from 4.16.5 to 4.16.12 because 4.16.12 had conveniently just been propagated from Debian Sid to Buster). And so far it appears that upgrade makes a large improvement for the RX 550. Previously for 4.16.5 the uptimes before a lock up occurred ranged from 7 hours to 2 days, but right now with heavy desktop use and a substantial number of runs of the 3D game, I haven't experienced a single lock up with 4.16.12 with current uptime since I booted 4.16.12 approaching 3 days. You may well conclude "problem already solved", but I normally run my computer 24/7 with reboots only when absolutely necessary. Therefore I would like to keep this bug report open for a while just to report the maximum uptimes (hopefully at least several months) I can achieve with this graphics card.
