The modem is a cellphone connected via bluetooth. Due to the nature of this connection, I expect stalls, tcp-timeouts, latency buildup, and similar. Tonight the link was exceptionally bad and I had something new, that worries me: Established a tunnel via novell-vpn, logged into the suse network via ssh. After typing a few commands, my laptop froze. I repeated this 3 times and captured a relevant portion from /var/log/messages. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

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? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

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. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

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.

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. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
