The test passes just fine. Inability to write 'orig_do_sleep' to tracing sysfs is strange. Would it be possible to log in to the machine, so I could take a look? Or provide the image of the broken system which I could run locally. CCing Libor, so he's aware. -- You are receiving this mail because: You are the assignee for the bug.
