https://bugzilla.kernel.org/show_bug.cgi?id=219773 --- Comment #9 from Frederic Bezies (fredbezies@xxxxxxxxx) --- Modification done. I tried with my external USB HDD copying big files. I do not have access of the previous USB peripheral . Here is the output while copying 2 big tar.xz archives (6 Go each). [11012.004194] sd 6:0:0:0: [sdb] 976773164 512-byte logical blocks: (500 GB/466 GiB) [11012.004519] sd 6:0:0:0: [sdb] Write Protect is off [11012.004523] sd 6:0:0:0: [sdb] Mode Sense: 23 00 00 00 [11012.004846] sd 6:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [11012.070815] sdb: sdb1 [11012.070970] sd 6:0:0:0: [sdb] Attached SCSI disk [11012.324232] xhci_hcd 0000:30:00.3: Stalled endpoint for slot 1 ep 2 [11355.077282] usb 4-1: USB disconnect, device number 2 [11355.166387] sd 6:0:0:0: [sdb] Synchronizing SCSI cache [11355.166436] sd 6:0:0:0: [sdb] Synchronize Cache(10) failed: Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK Weird there is no other output. I'll try another external USB SSD as soon as possible. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
