https://bugzilla.kernel.org/show_bug.cgi?id=205417 Bug ID: 205417 Summary: Files corruption ( fs/ext4/inode.c:3941 ext4_set_page_dirty+0x3e/0x50 [ext4] ) Product: File System Version: 2.5 Kernel Version: 5.3.8 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ext4 Assignee: fs_ext4@xxxxxxxxxxxxxxxxxxxx Reporter: the.dmol@xxxxxxxxx Regression: No Symptoms: after receiving the warning below I continued to work, but some processes with heavy I/O (namely g++), started to hang. I could kill them only via ctrl+c. The reboot program hanged too (no any reaction). Then I forced to turn off power and got corrupted files. 2019-11-04T12:31:44.706915+03:00 localhost kernel: [ 263.974691] WARNING: CPU: 3 PID: 138 at fs/ext4/inode.c:3941 ext4_set_page_dirty+0x3e/0x50
