A desktop PC is running Debian 11 with an AMD Ryzen CPU. The system has been running well, but now the following error messages have been seen :-
Message from syslogd@piglit at May 27 13:58:09 ... kernel:[2083218.760570] EXT4-fs (dm-0): failed to convert unwritten extents to written extents -- potential data loss! (inode 394119, error -30) [3135811:3135811:0527/135811.569191:ERROR:gpu_memory_buffer_support_x11.cc(49)] dri3 extension not supported. Message from syslogd@piglit at May 27 13:58:09 ... kernel:[2083218.760570] EXT4-fs (dm-0): failed to convert unwritten extents to written extents -- potential data loss! (inode 394119, error -30) Any thoughts about why the above is happening, please ? The Opera browser was running at the time. Subsequent to the above messages, it was found that neither the Opera or Chrome browser could be opened. Firefox has been opened but seems to run in a basic mode.
