--- Comment #88 from Guido (guido.iod...@gmail.com) --- (In reply to Guido from comment #87) > Created attachment 303184 [details] > kernel log (with patch on data.c applied) After several days of use I still did not have the 100% cpu busy problem but it gets worse. The system would not go to sleep or shut down (this happened several times and forced me to brutally shut down the computer), so checking the log I noticed several errors related to f2fs. I attach the log. Follows an extract of the log for your convenience nov 15 02:17:13 manjaro kernel: INFO: task f2fs_ckpt-259:3:233 blocked for more than 245 seconds. nov 15 02:17:13 manjaro kernel: Tainted: G U 6.0.8-1-MANJARO #1 nov 15 02:17:13 manjaro kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. nov 15 02:17:13 manjaro kernel: task:f2fs_ckpt-259:3 state:D stack: 0 pid: 233 ppid: 2 flags:0x00004000 nov 15 02:17:13 manjaro kernel: Call Trace: nov 15 02:17:13 manjaro kernel: <TASK> nov 15 02:17:13 manjaro kernel: __schedule+0x343/0x11c0 nov 15 02:17:13 manjaro kernel: ?
