https://bugzilla.kernel.org/show_bug.cgi?id=82201 kun.chen <kun.chen@xxxxxxxxxxxx> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution|--- |INVALID --- Comment #2 from kun.chen <kun.chen@xxxxxxxxxxxx> --- I already checked that this is because ext4 super block memory was corrupted, because we didn't set EXT4_FEATURE_RO_COMPAT_METADATA_CSUM, but it skip the checking and enter ext4_superblock_csum. ext4_super_block was stored in r1:c406d400, from stack the s_feature_ro_compat value is c53e05e6, so it can skip the checking in ext4_superblock_csum_set. And refer to r1 stack data, we already find it related to selinux. "And did this happen after an unclean shutdown (so the journal had to be replayed)" Yes, it happened after a software watchdog reset. I'm not sure whether the journal data corrupt related to memory corrupt, because next reboot it can mount successful. -- 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
