So far I tracked it: it works on -D '2004-12-08 12:00' and does not works with -D '2004-12-09 00:00' I guess time is by MSK timezone (my local time). There are a lot of changes between these dates. > Is it an ohci or uhci (or ehci) usb inerface? I think both. It strikes when only ehci umass device attached or when uhci mouse or bluetooth dongle connected. usb0: <Intel 82801DB (ICH4) USB controller USB-A> on uhci0 usb0: USB revision 1.0 usb1: <Intel 82801DB (ICH4) USB controller USB-B> on uhci1 usb1: USB revision 1.0 usb2: <Intel 82801DB (ICH4) USB controller USB-C> on uhci2 usb2: USB revision 1.0 ehci_pci_attach: companion usb0 ehci_pci_attach: companion usb1 ehci_pci_attach: companion usb2 usb3: EHCI version 1.0 usb3: companion controllers, 2 ports each: usb0 usb1 usb2 usb3: <EHCI (generic) USB 2.0 controller> on ehci0 usb3: USB revision 2.0 Looks like it is not USB-only problem, I have revert only USB code and it does not helps. So I suppose it is some kind of locking problem. -- Vladimir B. Grebenchikov vova_at_fbsd.ruReceived on Fri Jan 07 2005 - 22:03:18 UTC
