Hi,
After I finished using my USB HDD, I umount it. When unplug from my computer, there are the following output:
Nov 17 21:13:11 magf1 kernel: usb 1-5: USB disconnect, address 2 Nov 17 21:13:11 magf1 kernel: slab error in kmem_cache_destroy(): cache `scsi_cmd_cache': Can't free all objects Nov 17 21:13:11 magf1 kernel: [<c0104164>] dump_stack+0x23/0x27 (20) Nov 17 21:13:11 magf1 kernel: [<c0151ba5>] kmem_cache_destroy+0x106/0x194 (28) Nov 17 21:13:11 magf1 kernel: [<c02c99b5>] scsi_destroy_command_freelist+0x53/0x81 (28) Nov 17 21:13:11 magf1 kernel: [<c02ca866>] scsi_host_dev_release+0x43/0x164 (172) Nov 17 21:13:11 magf1 kernel: [<c0295b4d>] device_release+0x7c/0x80 (32) Nov 17 21:13:11 magf1 kernel: [<c0226b94>] kobject_cleanup+0x94/0x96 (32) Nov 17 21:13:11 magf1 kernel: [<c02276ba>] kref_put+0x46/0xf0 (40) Nov 17 21:13:11 magf1 kernel: [<c0226bd2>] kobject_put+0x25/0x29 (16) Nov 17 21:13:11 magf1 kernel: [<d8880146>] usb_stor_release_resources+0x7e/0x133 [usb_storage] (24) Nov 17 21:13:11 magf1 kernel: [<d88806d6>] storage_disconnect+0x9a/0xa8 [usb_storage] (16) Nov 17 21:13:11 magf1 kernel: [<d88a118c>] usb_unbind_interface+0x8b/0x8d [usbcore] (28) Nov 17 21:13:11 magf1 kernel: [<c0296d92>] device_release_driver+0x86/0x88 (28) Nov 17 21:13:11 magf1 kernel: [<c0296f98>] bus_remove_device+0x56/0x86 (20) Nov 17 21:13:11 magf1 kernel: [<c0295f91>] device_del+0x4f/0x88 (20) Nov 17 21:13:11 magf1 kernel: [<d88a947c>] usb_disable_device+0xd1/0x172 [usbcore] (44) Nov 17 21:13:11 magf1 kernel: [<d88a3c97>] usb_disconnect+0xb0/0x187 [usbcore] (44) Nov 17 21:13:11 magf1 kernel: [<d88a5309>] hub_port_connect_change+0x471/0x4a0 [usbcore] (72) Nov 17 21:13:11 magf1 kernel: [<d88a5779>] hub_events+0x441/0x52d [usbcore] (76) Nov 17 21:13:11 magf1 kernel: [<d88a589c>] hub_thread+0x37/0x120 [usbcore] (96) Nov 17 21:13:11 magf1 kernel: [<c0101329>] kernel_thread_helper+0x5/0xb (690024468) Nov 17 21:13:11 magf1 kernel: --------------------------- Nov 17 21:13:11 magf1 kernel: | preempt count: 00000001 ] Nov 17 21:13:11 magf1 kernel: | 1-level deep critical section nesting: Nov 17 21:13:11 magf1 kernel: ---------------------------------------- Nov 17 21:13:11 magf1 kernel: ..

On linux-2.6.6/2.6.7 and Fedora Core 2, My USB HDD is working properly. On realtime preempt kernel, I have such problem.
