it worked upon the first try, and indeed my testbox crashed within 10 seconds:
BUG: Unable to handle kernel NULL pointer dereference BUG: Unable to handle kernel NULL pointer dereference at virtual address 00000006 printing eip: 00000006 *pde = 00000000 Oops: 0000 [#1] PREEMPT Modules linked in: CPU: 0 EIP: 0060:[<00000006>] Not tainted VLI EFLAGS: 00010286 (2.6.12-RT-V0.7.51-30-debug) EIP is at 0x6 eax: c057fef8 ebx: c0614340 ecx: c04490b8 edx: 00000001 esi: c057ff34 edi: c0135d52 ebp: c057ff54 esp: c057ff3c ds: 007b es: 007b ss: 0068 preempt: 20000002
it was enough to "ssh 10.0.0.1" from the client, and typing "yes" would trigger the crash very soon.
thanks for the instructions - now i can start debugging this :-)
