https://bugzilla.kernel.org/show_bug.cgi?id=215712 Christian Kujau (lists@xxxxxxxxxxxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |lists@xxxxxxxxxxxxxxx --- Comment #3 from Christian Kujau (lists@xxxxxxxxxxxxxxx) --- A 5.17 kernel *is* able to mount the image here, but it takes quite some time to complete: ======================================= $ time mount -v -t ext4 -o loop,ro,debug tmp.img /mnt/disk/ mount: /dev/loop0 mounted on /mnt/disk. real 1m32.694s user 0m0.008s sys 1m32.665s ======================================= During that time the CPU is spinning like crazy, but I don't know how to debug this further as to why it's spinning. perf comes to mind, but maybe something more ext4 specific is more useful here. dmesg shows, for this mount operation: ======================================= [ 188.269405] [EXT4 FS bs=1024, gc=2, bpg=8192, ipg=2048, mo=a802c818, mo2=0002] [ 280.932637] EXT4-fs (loop0): mounted filesystem with ordered data mode. Quota mode: disabled. [ 595.249319] EXT4-fs (loop0): error count since last fsck: 1 [ 595.250559] EXT4-fs (loop0): initial error at time 1647888893: ext4_mb_generate_buddy:756 [ 595.253403] EXT4-fs (loop0): last error at time 1647888893: ext4_mb_generate_buddy:756 ======================================= @Ming, can you share details on how the image has been modified? -- You may reply to this email to add a comment.
