Hi. It's me again. May I bother you with another bug? (^_^;) The machine is a Lenovo X61 Tablet, a tablet PC with Intel GM965 / ICH8-M. It has a cardbus slot (32bit PCI), Ricoh RL5C476 II (VEN_1180 DEV_0476). The card is a VIA VT6421 (VEN_1106 DEV_3249) SATA/PATA controller. The card has 2 SATA ports and no PATA. ---- CARD INSERTED ---- [ 68.118063] pcmcia_socket pcmcia_socket0: pccard: CardBus card inserted into slot 0 [ 68.121922] pci 0000:06:00.0: [1106:3249] type 00 class 0x010400 [ 68.121972] pci 0000:06:00.0: reg 0x10: [io 0x0af0-0x0aff] [ 68.121996] pci 0000:06:00.0: reg 0x14: [io 0x0a70-0x0a7f] [ 68.122018] pci 0000:06:00.0: reg 0x18: [io 0x01f0-0x01ff] [ 68.122039] pci 0000:06:00.0: reg 0x1c: [io 0x0170-0x017f] [ 68.122059] pci 0000:06:00.0: reg 0x20: [io 0xcc00-0xcc1f] [ 68.122080] pci 0000:06:00.0: reg 0x24: [io 0x8c00-0x8cff] [ 68.122419] pci 0000:06:00.0: BAR 5: assigned [io 0x4000-0x40ff] [ 68.122438] pci 0000:06:00.0: BAR 4: assigned [io 0x4400-0x441f] [ 68.122451] pci 0000:06:00.0: BAR 0: assigned [io 0x4420-0x442f] [ 68.122465] pci 0000:06:00.0: BAR 1: assigned [io 0x4430-0x443f] [ 68.122478] pci 0000:06:00.0: BAR 2: assigned [io 0x4440-0x444f] [ 68.122491] pci 0000:06:00.0: BAR 3: assigned [io 0x4450-0x445f] [ 68.122639] sata_via 0000:06:00.0: version 2.6 [ 68.122662] sata_via 0000:06:00.0: enabling device (0000 -> 0001) [ 68.122879] sata_via 0000:06:00.0: routed to hard irq line 0 [ 68.122903] [79] sata_via:svia_configure:635: sata_via 0000:06:00.0: enabling SATA hotplug (0x0) [ 68.124012] scsi host6: sata_via [ 68.126042] scsi host7: sata_via [ 68.128757] scsi host8: sata_via [ 68.128927] ata6: SATA max UDMA/133 port i16@0x4420 bmdma 0x4400 irq 16 [ 68.128938] ata7: SATA max UDMA/133 port i16@0x4430 bmdma 0x4408 irq 16 [ 68.128944] ata8: PATA max UDMA/133 port i16@0x4440 bmdma 0x4410 irq 16 [ 68.129071] hardreset, Online=>Offline [ 68.130162] resume, do loop [ 68.348135] resume, after do loop [ 68.353240] debounce, SCR=0x0 [ 68.358342] debounce, SCR=0x0 ...
