I'm seeing the following with syncppp under 2.5.69:
1. When syncppp tries to send a control protocol packet,
I see the following kernel messages:
Badness in local_bh_enable at kernel/softirq.c:105
Call Trace:
[<c01254b4>] local_bh_enable+0x84/0x90
[<c02dbbc0>] dev_queue_xmit+0x1c0/0x250
[<cc82fd18>] sppp_lcp_open+0x78/0x90 [syncppp]
[<cc82fe3d>] sppp_cp_timeout+0xad/0xd0 [syncppp]
[<cc82fd90>] sppp_cp_timeout+0x0/0xd0 [syncppp]

[<c0108f90>] default_idle+0x0/0x40
[<c010bc82>] apic_timer_interrupt+0x1a/0x20
This appears the indicate that dev_queue_xmit() can't
be called with local interrupts disabled (which is the
case as a spinlock is held when this call is made).
It looks like a lot of reworking is necessary if this is true.
2. When network packets are received I see the following message:
[<c0121e65>] fix old protocol handler sppp_rcv+0x0/0x1e [syncppp]!
Any docs covering what needs to be done for this one?
Thanks,
Paul
