It keeps freezing. Had it twice today while on the train. kernel-debug installed. sysrq enabled. I'll try to get proper crashdump/process listings next time it freezes. Is there a way to get to a text console after it freezes? Seife, looks like this freeze happens while using btusb. $ lsmod | grep usb hci_usb 31900 0 btusb 23956 3 bluetooth 74212 9 bnep,rfcomm,l2cap,hci_usb,btusb usbcore 164812 5 hci_usb,btusb,ehci_hcd,uhci_hcd $ rpm -q btusb-kmp-pae btusb-kmp-pae-0.1_2.6.25.4_10-3 I did a flood ping and moved the phone 5, 10, 15, 20m away, until the ping no longer got through I get 'No buffer space available', which is fully recoverable by moving the phone closer. pings just resume fine. Switching off the phone while transfer is in progress, gives 'Network is unreachable' and a dropped connection. Just as it should. I cannot reproduce any freezes today. So while using btusb it did not freeze. It might well be that after the next reboot, you'll be using hci_usb again. Please configure that via modprobe.conf, retry with hci_usb only and with btusb only. I'd guess that the freezes happen with hci_usb only. That both modules are loaded is a bug in the btusb-kmp package, i will fix that, but I think it is "mostly harmless" - it is just not possible to predict which module will be actually used. Adding Pavel to CC, since he has already experienced similar problems. Switching modules, rebooting using hci_usb. Tried my series of tricks, no crash either. Hmm, so btusb has problems and hci_usb works... bad :-(. How do you draw that conclusion? It seems to me that the crash is not reproducible and might have happened with btusb or hci_usb and we don't know which because both modules were loaded. May be related to 414206 So you think this is a network bug and bluetooth merely triggers it? I can replicate a hang with btusb hanging in btusb_intr_complete() I can semireliably trigger it compiling with CONFIG_BT_HCIBTUSB_DEBUG and doing obex transfers of large files.

another freeze today ca 1 minute after resume from ram.
I was able to start bluetooth modem connection, google a bit, then sudden death.
I have
usbcore 164812 4 hci_usb,uhci_hcd,ehci_hcd
but no btusb.
This may well be the double free issue fixed in 2.6.27 Maybe you can backport this fix ? The fix has been backported and applied. Please reopen if it happens after the next kernel update.
