Hi, When I restart the networking (service network stop ; service network start) on two of our servers, the machine kernel panics and dies. The machines are Dual Intel Xeon EM64T 3.6Ghz with 4 Broadcom NICs (2 onboard, 2 cards) (IBM x346's) running Fedora Core 3 x86_64 - kernel is 2.6.10-1.770_FC3smp. The output at the console is below: Code: F2AE488B44240848F7E1448D69FF488378600048 RIP <ffffffff801a3ae0> (remove_proc_entry+63) RSP <00000100BFF27E78> CR2: 00000000290101ef <3> debug: sleeping function called from invalid context at include/linux/rwsem.h:43 in_atomic:(1), irqs_disabled:(0) call trace: <irq> <ffffffff8012e539> (__might_sleep+171) <ffffffff80134047) (profile_task_exit+31) <ffffffff801355cf> (do_exit+34) <ffffffff8010f8df> (oops_end+38) <ffffffff8012003d> (do_page_fault+1222) <ffffffff802c9c6> (igmpv3_newpack+129) <ffffffff8010eb8d> (error_exit+0) <ffffffff801a3ae0> (remove_proc_entry+63) <ffffffffa0122ee4> (:ipv6:snmp6_unregister_dev+54) <ffffffffa010497d> (:ipv6:in6_dev_finish_destroy+133) <ffffffff802a1ce1> (dft_destroy+124) <ffffffff802a1d37> (dft_run_gc+0) <ffffffff802a1d9b> (dst_run_gc+100) <ffffffff8013b6b5> (run_timer_softirq+356) <ffffffff80138088> (__do_softirq+88) <ffffffff80138131> (do_softirq+49) <ffffffff8010e9f1> (apic_timer_interrupt+133) <EOI> <ffffffff8010c78c> (mwait_idle+86) <ffffffff8010c71c> (cpu_idle+26) Kernel panic - not syncing: Aiee, killing interrupt handler! Can anyone recommend a solution for this problem? Regards, -- Alex
