2.6.0-test3(-mm1) : Alcatel USB speedtouch modem unusable

Hi,

I'm using the Alcatel USB ADSL speedtouch modem with the user space driver. It was running fine with 2.6.0-test2 (and older kernel).

[root@tigre01 root]# Using interface ppp0
Connect: ppp0 <--> /dev/pts/4
Remote message: CHAP authentication success, unit 405 local IP address 193.253.203.209
remote IP address 193.253.203.1
primary DNS address 193.252.19.3
secondary DNS address 193.252.19.4

Now, something seems to be broken with 2.6.0-test3 (and 2.6.0-test3-mm1)

I didn't change anything to my configuration and to my .config file. Any idea?
