Alcatel Speedtouch locks system on shutdown

Alcatel Speedtouch locks system on shutdown

Post by Alexander Linkenbac » Sat, 17 Jul 2004 04:56:29



Hi
Whenever I shutdown/reboot my system with my Alcatel Speedtouch USB plugged
in my system freezes when sending all processes the TERM signal. When it is
disconnected or the network simply disabled with rcnetwork stop before
anually, the system shuts down smoothely. This does only happen with the
latest kernel 2.6.5-7.95-smp and with the older -7.75-smp. When I revert to
2.6.4-52-smp from the installation dvd it shuts down ok but I get random
freezes with a kernel panic which might or might not be a different issue.
The dsl does however work perfectly otherwise.

Can anyone help?

Hallo
Wenn ich mein System herunterfahre oder neustarte friert mein Rechner bei
der Meldung sending all processes the TERM signal komplett ein, wenn mein
Alcatel Speedtouch USB eingest?pselt ist. Ist das Modem entst?pselt bzw.
das Netzwerk manuell mit rcnetwork stop vorher abgeschaltet, f?hrt der
Rechner sauber runter. DSL (pppoam mit BT Internet) funktioniert ansonsten
absolut problemlos. Problem tritt auf mit Kernel Version 2.6.5-7.95-smp und
trat auf mit 2.6.5-7.75-smp. 2.6.4-52-smp von der Installations-DVD f?hrt
zwar sauber runter, aber ich bekomme dafr kernel panic Abstrze w?hrend
des Betriebes, was ebensogut ein v?llig anderes Problem sein k?nnte. Kann
jemand helfen?

1. Alcatel Speedtouch USB freezes system on shutdown

Hi
When I shutdown my system with the Alcatel Speedtouch USB connected it
freezes completely when sending all processes the term signal. With
rchotplug stop and the modem unplugged from the USB port it shuts down
nicely. I have got two independent USB controllers but swapping the modem
makes no difference.
Here are the last messages from console 10:

System is a dual Athlon MP 1400, AMD A7M266-D, SuSE 9.1, kernel
2.6.5-7.95-smp. (2.6.4something worked fine on shutdown but froze randomly
possibly with some IRQ issue while running. Could be some sort of same
problem, could be not.)

Am I really the only one with that problem? If yes it might be some f****d
up hardware, but I could only isolate the problem down to mainboard,
processor, RAM, USB and Speedtouch by disconnecting the rest.

Help very much appreciated.
