https://bugzilla.kernel.org/show_bug.cgi?id=76261 --- Comment #12 from kun.chen <kun.chen@xxxxxxxxxxxx> --- Hi Theodore, How about these informations in the kmsg: [76.209728]-(3)[1:init]SysRq: -(3)[1:init]Emergency Remount R/O [76.282979] (3)[21:kworker/3:0]Emergency Remount Complete ...... [80.272068] (3)[3075:kworker/u8:5]EXT4-fs (mmcblk0p15): ext4_da_writepages: jbd2_start: 1024 pages, ino 131067; err -30 ...... [85.407025] (1)[3075:kworker/u8:5]EXT4-fs (mmcblk0p15): ext4_da_writepages: jbd2_start: 1024 pages, ino 131067; err -30 ...... [90.601634] (0)[3075:kworker/u8:5]EXT4-fs (mmcblk0p15): ext4_da_writepages: jbd2_start: 1024 pages, ino 131067; err -30 "ext4_da_writepages: jbd2_start: 1024 pages, ino 131067; err -30" was presented every 5 seconds, so means these dirty pages old than 30 seconds? If so, these datas were written before shutdown, but did not be written out after sync() and emergency_remount(), does it normal? -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
