https://bugzilla.kernel.org/show_bug.cgi?id=89511 --- Comment #35 from Alan Stern <stern@xxxxxxxxxxxxxxxxxxx> --- Yes, your problem is related to the journal. When ext4 adds an entry to the journal, it sends a SYNCHRONIZE CACHE command to make sure all data sent to the drive's cache has been stored properly. Your device doesn't like SYNCHRONIZE CACHE, so the journal write fails. To fix the problem, you need to use a later kernel version (like 3.18) or use a different USB storage device. -- 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
