I've seen the same symptoms on my parents machine during the last 1-2 months --> ie. keyboard hangs completely, mouse works and the host either hangs completely sooner or later with only the following usb debug messages in the logs (pasted below). I believe that there is certainly some sort of bug in cinergyT2-driver as I've not seen the hang happen whenever the cinergyT2 usb-receiver has been disconnected from the machine. Host configuration is: 2.6.22-rc4-git4 kernel + latest DVB drivers from v4l-dvb tree (previously also tested with FC6 kernels with same symptoms) MythTV-software (from devel SVN) Asus P4P800-E motherboard (ich5 & PDC20378 sata-controllers) 1GB ram Intel P4 2.8MHz Terratec Cinergy T2 dvb-t receiver Regards, Tomi Orava -------------------------------------------------- ehci_hcd 0000:00:1d.7: devpath 1 ep2in 3strikes hub 1-0:1.0: state 7 ports 8 chg 0000 evt 0002 ehci_hcd 0000:00:1d.7: GetStatus port 1 status 001002 POWER sig=se0 CSC hub 1-0:1.0: port 1, status 0100, change 0001, 12 Mb/s usb 1-1: USB disconnect, address 2 usb 1-1: unregistering device usb 1-1: usb_disable_device nuking all URBs ehci_hcd 0000:00:1d.7: shutdown urb f6c9a3c0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a340 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a2c0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a240 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f71a6c40 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f7e7f0c0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c37dc0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c37e40 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f71a6d40 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9af40 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f71a61c0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9ae40 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9adc0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9ad40 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9acc0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9ac40 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9abc0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9ab40 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9aac0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9aa40 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a9c0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a940 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a8c0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a840 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a7c0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a740 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a6c0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a640 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a5c0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a540 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a4c0 pipe c0010280 ep2in-bulk ehci_hcd 0000:00:1d.7: shutdown urb f6c9a440 pipe c0010280 ep2in-bulk cinergyT2: cinergyt2_submit_stream_urb(): urb submission failed (err = -19)! last message repeated 31 times --------------------------------------------------------------------- -- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
