My laptop comes to life reliably > after the stall. Thanks Bengt, that sounds encouraging, I'll try it tomorrow. Now running 8.2-RELEASE GENERIC, so I'm wondering whether I can just build a kernel with 'nodevice uchi' (the T23 only has USB 1.1 anyway) then load uhci.ko at boot, unload before suspend, reload after resume? Or 'nodevice usb' then load it and uhci too, as usb(4) seems to suggest? I'm not really up on the newer usb stuff, uhci(4) is from April 2005 and doesn't mention the 82801CA/CAM controller either .. t23# grep -i usb /var/run/dmesg.boot uhci0: <Intel 82801CA/CAM (ICH3) USB controller USB-A> port 0x1800-0x181f irq 11 at device 29.0 on pci0 usbus0: <Intel 82801CA/CAM (ICH3) USB controller USB-A> on uhci0 uhci1: <Intel 82801CA/CAM (ICH3) USB controller USB-B> port 0x1820-0x183f irq 11 at device 29.1 on pci0 usbus1: <Intel 82801CA/CAM (ICH3) USB controller USB-B> on uhci1 uhci2: <Intel 82801CA/CAM (ICH3) USB controller USB-C> port 0x1840-0x185f irq 11 at device 29.2 on pci0 usbus2: <Intel 82801CA/CAM (ICH3) USB controller USB-C> on uhci2 usbus0: 12Mbps Full Speed USB v1.0 usbus1: 12Mbps Full Speed USB v1.0 usbus2: 12Mbps Full Speed USB v1.0 ugen0.1: <Intel> at usbus0 uhub0: <Intel UHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus0 ugen1.1: <Intel> at usbus1 uhub1: <Intel UHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus1 ugen2.1: <Intel> at usbus2 uhub2: <Intel UHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus2 cheers, Ian --0-1678088716-1309187665=:72504--
