hello again,

actually, the last _two_ commands set up the kernel for panic. please see attached script; running should produce this console message:
HTB init, kernel part version 3.17 Ingress scheduler: Classifier actions prefered over netfilter
shortly then, the kernel will panic (ifconfig shows up to 500KiB RX before).
with vga selection enabled, and a long;) piece of paper, this is produced: (omissions marked [...] - these numbers are very hard to not misread)
Unable to handle kernel NULL pointer dereference at virtual address 0000000d printing eip: c02080f60 *pde = 00000000 Oops: 0000 [#1] Modules linked in: [...] [...] Call Trace: ip_rcv_finish ing_hook nf_iterate ip_rcv_finish ip_rcv_finish ing_hook_slow ip_rcv_finish ip_rcv ip_rcv_finish netif_receive rtl8139_rx rtl8139_poll net_rx_action __do_softirq do_IRQ common_interrupt default_idle cpu_idle start_kernel unknown_bootoption Code: 8b 43 0c 39 f0 74 43 3d 00 03 00 00 74 3c 8b 1b 85 db 75 ec <0>Kernel panic : Fatal exception in interrupt In interrupt handler - not syncing
eof.
another time, running iptraf, identical Oops, but first line reads:
Unable to handle kernel paging request at virtual address 000a0f0d [...] EIP is at ingress_enqueue+0x20/0x90 [...]
the traffic shaping of upstream packets does not panic the kernel; I also tried a different timer source, to no success.
regards,
peter
