[expert-it] Kernel Oops and pppd

[Gianluca Toso]

Hi, I'm using mandrake 8.2 on a PPC G3 (ibook 2):

cpu             : 750CX
temperature     : 12 C (uncalibrated)
clock           : 499MHz
revision        : 34.20 (pvr 0008 2214)
bogomips        : 996.14
machine         : PowerBook4,1
motherboard     : PowerBook4,1 PowerBook2,2 MacRISC2 MacRISC Power
Macintosh
L2 cache        : 256K unified
memory          : 256MB
pmac-generation : NewWorld

The kernel is the default one as providedby mandrake:
kernel-2.4.18.8.1mdk-1-3mdk
ppp-2.4.1-3mdk

I'm using the internal modem:

macserial: i2c-modem detected, id: 1
PowerMac Z8530 serial driver version 2.0
tty00 at 0xd18c0020 (irq = 22) is a Z8530 ESCC (internal modem)
tty01 at 0xd2b39000 (irq = 23) is a Z8530 ESCC

Everything goes well if I connect to a normal ISP, but if I connect to a
linux machine with mgetty+ppp after some minutes kernel errors occur.

This happens either using kppp or wvdial.. any hints?
Kernel message attached.

Below are modules loaded dring a normal ISP connection (and in the other
case, I suppose):
