Are there instructions so we can build the ext4_combined from source? That's going to be needed if we are going to be able to run the binary under a debugger, and versus a patched kernel to verify the fix. Also, can you give us a stack dump so we might have some kind of hint what's going on? -- You are receiving this mail because: You are watching the assignee of the bug.
