I have an USB HDD with some mounted partitions. I hibernate using swsusp and resume. Now the device is unavailable though there is no error messages in dmesg. Reads from /dev/sdd just block and ls for a mounted directory is blocked in the following path: [ 1800.553697] ls D c0252908 0 11582 7435 0x00000000 [ 1800.553704] f1446cd4 00200082 f1446c90 c0252908 f0a3e280 f0a3e4f0 f0a3e4ec c04f2ec0 [ 1800.553713] c04f2ec0 f0a3e4ec c04f2ec0 c04f2ec0 c04f2ec0 c851f8fc 00000176 c84ff43d [ 1800.553722] 00000176 f0a3e280 00000001 f0a3e280 c3408ec0 f1446d24 f1446ce4 c035e3db [ 1800.553731] Call Trace: [ 1800.553743] [<c0252908>] ? kobject_put+0x37/0x3c [ 1800.553750] [<c035e3db>] io_schedule+0x5a/0x93 [ 1800.553758] [<c01b984c>] sync_buffer+0x33/0x37 [ 1800.553762] [<c035e7b1>] __wait_on_bit+0x34/0x5b [ 1800.553767] [<c01b9819>] ? sync_buffer+0x0/0x37 [ 1800.553773] [<c01b9819>] ? sync_buffer+0x0/0x37 [ 1800.553777] [<c035e873>] out_of_line_wait_on_bit+0x9b/0xa3 [ 1800.553786] [<c01401fc>] ? wake_bit_function+0x0/0x37 [ 1800.553791] [<c01b97e1>] __wait_on_buffer+0x19/0x1c [ 1800.553817] [<f947a9a5>] ext4_find_entry+0x2f5/0x462 [ext4] [ 1800.553826] [<c0125dea>] ? dequeue_task+0xaa/0xb9 [ 1800.553832] [<c035f807>] ? _raw_spin_unlock_irq+0x15/0x20 [ 1800.553838] [<c0146a85>] ? ktime_get_ts+0xc0/0xca [ 1800.553844] [<c035f7e7>] ? _raw_spin_unlock_irqrestore+0x16/0x21 [ 1800.553862] [<f947ab3a>] ext4_lookup+0x28/0xb6 [ext4] [ 1800.553869] [<c01a5255>] d_alloc_and_lookup+0x3f/0x56 [ 1800.553874] [<c01a533a>] do_lookup+0x94/0xcb [ 1800.553880] [<c01a6b2f>] link_path_walk+0x231/0x358 [ 1800.553885] [<c01a6d1d>] path_walk+0x50/0xb0 [ 1800.553890] [<c01a6e53>] do_path_lookup+0x21/0x6f [ 1800.553895] [<c01a766a>] user_path_at+0x39/0x5f [ 1800.553901] [<c0185811>] ? __do_fault+0x377/0x3a3 [ 1800.553908] [<c02a389c>] ? tty_ioctl+0x3d4/0x6b6 [ 1800.553914] [<c017a22e>] ? lru_cache_add_lru+0x22/0x24 [ 1800.553921] [<c01a143f>] vfs_fstatat+0x2d/0x54 [ 1800.553926] [<c018691d>] ? handle_mm_fault+0x9db/0xa02 [ 1800.553932] [<c01a14aa>] vfs_lstat+0x16/0x18 [ 1800.553937] [<c01a14c0>] sys_lstat64+0x14/0x28 [ 1800.553944] [<c011b652>] ? do_page_fault+0x1e4/0x242 [ 1800.553949] [<c011b680>] ? do_page_fault+0x212/0x242 [ 1800.553955] [<c035fbec>] syscall_call+0x7/0xb This is latest Linus tree (32163f4b2cef28a5aab8b226ffecfc6379a53786). There was no such thing in .35 or earlier kernels. I can bisect this if needed.

I tried, but unfortunately I can't reproduce this anymore even with kernels that surely had this behavior.
Closing as unreproducible. Please reopen if you can reproduce again.
