It's able to see the external SATA harddisk. On initial boot, I'm seeing the following OOPS. 2010-06-14T16:43:21.077256+08:00 boston kernel: scsi 6:0:0:0: Direct-Access ATA SAMSUNG MCCOE64G PS10 PQ: 0 ANSI: 5 2010-06-14T16:43:21.077258+08:00 boston kernel: sd 6:0:0:0: [sdb] 125045424 512-byte logical blocks: (64.0 GB/59.6 GiB) 2010-06-14T16:43:21.077260+08:00 boston kernel: sd 6:0:0:0: Attached scsi generic sg1 type 0 2010-06-14T16:43:21.077261+08:00 boston kernel: sd 6:0:0:0: [sdb] Write Protect is off 2010-06-14T16:43:21.077264+08:00 boston kernel: sd 6:0:0:0: [sdb] Mode Sense: 00 3a 00 00 2010-06-14T16:43:21.077266+08:00 boston kernel: sd 6:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA 2010-06-14T16:43:21.077267+08:00 boston kernel: sdb: sdb1 2010-06-14T16:43:21.077268+08:00 boston kernel: sd 6:0:0:0: [sdb] Attached SCSI disk 2010-06-14T16:43:21.077270+08:00 boston kernel: ------------[ cut here ]------------ 2010-06-14T16:43:21.077272+08:00 boston kernel: WARNING: at fs/sysfs/dir.c:451 sysfs_add_one+0x82/0x95() 2010-06-14T16:43:21.077273+08:00 boston kernel: Hardware name: 5413FGA 2010-06-14T16:43:21.077276+08:00 boston kernel: sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:1c.3/0000:05:00.0/slot' 2010-06-14T16:43:21.077277+08:00 boston kernel: Modules linked in: 2010-06-14T16:43:21.077279+08:00 boston kernel: Pid: 1, comm: swapper Not tainted 2.6.35-rc2 #69 2010-06-14T16:43:21.077280+08:00 boston kernel: Call Trace: 2010-06-14T16:43:21.077282+08:00 boston kernel: [<ffffffff8103127c>] ? warn_slowpath_common+0x78/0x8c 2010-06-14T16:43:21.077284+08:00 boston kernel: [<ffffffff8103132f>] ? warn_slowpath_fmt+0x45/0x4a 2010-06-14T16:43:21.077286+08:00 boston kernel: [<ffffffff810dcf35>] ? sysfs_add_one+0x82/0x95 2010-06-14T16:43:21.077288+08:00 boston kernel: [<ffffffff810ddc58>] ? sysfs_do_create_link+0xdd/0x151 2010-06-14T16:43:21.077291+08:00 boston kernel: [<ffffffff810dc869>] ? sysfs_add_file_mode+0x56/0x7d 2010-06-14T16:43:21.077293+08:00 boston kernel: [<ffffffff811c82c7>] ? pci_create_sysfs_dev_files+0x2e4/0x3f6 2010-06-14T16:43:21.077295+08:00 boston kernel: [<ffffffff8173af12>] ? pci_sysfs_init+0x1b/0x4c 2010-06-14T16:43:21.077296+08:00 boston kernel: [<ffffffff8173aef7>] ? pci_sysfs_init+0x0/0x4c 2010-06-14T16:43:21.077298+08:00 boston kernel: [<ffffffff810001e0>] ? do_one_initcall+0x4f/0x149 2010-06-14T16:43:21.077300+08:00 boston kernel: [<ffffffff8171f696>] ? kernel_init+0x14b/0x1d1 2010-06-14T16:43:21.077301+08:00 boston kernel: [<ffffffff81002ca4>] ? kernel_thread_helper+0x4/0x10 2010-06-14T16:43:21.077303+08:00 boston kernel: [<ffffffff8171f54b>] ? kernel_init+0x0/0x1d1 2010-06-14T16:43:21.077306+08:00 boston kernel: [<ffffffff81002ca0>] ? kernel_thread_helper+0x0/0x10 2010-06-14T16:43:21.077307+08:00 boston kernel: ---[ end trace 962a14d7e07fcb71 ]--- A second problem relating to the ExpressCard is ejecting and inserting the card.

Or perhaps I be asking ... is there a utility to stop the interface before pulling off the card? And often, inserting the card does not make the kernel detect the event that the card has been inserted. I've to try a few times before seeing any message. I've disabled rsyslog so that it shows repeated logs. I'm testing it on Linux-2.6.35-rc2, but I think it's happening on older versions as well. I'm using CONFIG_HOTPLUG_PCI_ACPI so that it can detect the hotplug events on my X201s Lenovo notebook.
