https://bugzilla.kernel.org/show_bug.cgi?id=215740 --- Comment #38 from Ferry Toth (ferry.toth@xxxxxxxxxxxx) --- With Catalin Marinas's suggestion "force the kmalloc() min align to cache_line_size()" + attachment 305473 root@yuna:~# journalctl -k | grep hub kernel: usbcore: registered new interface driver hub kernel: hub 1-0:1.0: USB hub found kernel: usb usb1: hub buffer at 71c7180, status at 71c71c0 kernel: hub 1-0:1.0: 1 port detected kernel: hub 2-0:1.0: USB hub found kernel: usb usb2: hub buffer at 71c79c0, status at 71c7a00 kernel: hub 2-0:1.0: 1 port detected kernel: hub 1-1:1.0: USB hub found kernel: usb 1-1: hub buffer at 65b36c0, status at 6639340 kernel: hub 1-1:1.0: 7 ports detected and stack trace goes away. IOW the 2 root hub kmalloc() are now also aligned to the cache line size, even though these never triggered the stack trace. Strange: hub's status is aligned far away from hub buffer. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
