Hi!
(As I don't know who is responsible for the ISDN driver in the
pre-2.0.34 series, I'm writing this report to both the linux-kernel
mailing-list and the isdn4linux newsgroup)
I'm getting the following "oops" with linux-2.0.34pre14 and I think
it is related to the isdn4l driver:

Using "ksymoops", I get:

Note that the oops occured in "icmp_send", immediately after isdn_net
tried to send some ICMP messages, so I think the ISDN driver must be
involved somehow. The machine didn't crash completely, I still could
use the ISDN interface for incoming calls.
I'm using the HiSax Teles driver, compiled as modules.
Here's the relevant section from the kernel configuration:
#
# ISDN subsystem
#
CONFIG_ISDN=m
CONFIG_ISDN_PPP=y
CONFIG_ISDN_PPP_VJ=y
CONFIG_ISDN_MPP=y
CONFIG_ISDN_AUDIO=y
CONFIG_ISDN_DRV_ICN=m
CONFIG_ISDN_DRV_PCBIT=m
CONFIG_ISDN_DRV_HISAX=m
CONFIG_HISAX_EURO=y
# CONFIG_HISAX_1TR6 is not set
CONFIG_HISAX_16_0=y
CONFIG_HISAX_16_3=y
CONFIG_HISAX_AVM_A1=y
CONFIG_HISAX_ELSA_PCC=y
# CONFIG_HISAX_ELSA_PCMCIA is not set
CONFIG_HISAX_IX1MICROR2=y
CONFIG_ISDN_DRV_SC=m
CONFIG_ISDN_DRV_AVMB1=m
CONFIG_ISDN_DRV_AVMB1_VERBOSE_REASON=y
The HiSax Module is loaded by kerneld, using the following options:
# ISDN4Linux - Module
# I/O für Teles.S0 ISDN-Karte (mem=0xb0000, irq=5, D-Kanal Prot=EDSS1)
options hisax mem=0xb0000 irq=5 type=2 protocol=2 id=teles
I'm using a setup where I don't have an outgoing telephone number
added to ISDN interface isdn0 (it's used for incoming calls only).
This is the output from "isdnctrl isdn0":
