Yes although getting people seeing to test with might_sleep() checks in
the tty layer demonstrate the tty layer isn't calling into ppp with irqs
disabled when it shouldn't so I'm at a loss as to whether this is a
network bug, a scheduler bug or something else.

The schedule error in __tasklet_schedule() is itself rather peicular.

Looks like I can't reproduce with rc1-git5 (after several hours)...
I'll try -git3,-git4.

Bug-Entry       : http://bugzilla.kernel.org/show_bug.cgi?id=13652
Subject         : scheduling while atomic: pptpgw

Rafael, I'm not sure we need 'scheduling while atomic: pptpgw' bug.
Initially BUG 13522 was named "BUG: scheduling while atomic: pptpgw" 
and renamed to "BUG: scheduling while atomic" since I was not sure wheter this is ppp or scheduler bug...

Which doesn't reschedule - sorry at this point I can't help you any
further. The traces make no sense.

can you enable CONFIG_DEBUG_INFO, and then run this through
scripts/markup_oops.pl ? With a bit of luck it'll point to the exact
code that's going wrong...

I think I'm having the same issue here. Both vpnc and KVM (using tap0)
not working on 2.6.31-rc1. I think it worked before <2.6.30.

i've tried the patches as mentioned in
http://bugzilla.kernel.org/show_bug.cgi?id=13627, but still not
working.

Thanks,
Jeff.

So you mean that 71f9dacd2e4d233029e9e956ca3f79531f411827 doesn't
work? Does reverting d55d87fdff8252d0e2f7c28c2d443aee17e9d70f help?

If not can you elaborate on what you mean by not working?

My Linux git already has these two commits, and I tested it with vpnc
(0.5.3) and it connected, but can't ping or ssh to remote. It was
working prior to 2.6.30.

Tested reverting d55d87fdff8252d0e2f7c28c2d443aee17e9d70f, but still
no good. Also reverted 71f9dacd2e4d233029e9e956ca3f79531f411827, still
no good.

> If not can you elaborate on what you mean by not working?

It seems the tunnel is not setup correctly, but I'll have to revert
back to 2.6.29+ to verify.

On kvm (again, it could be KVM which I'm not 100% sure. kvm-87),  it
won't ping to/from the guest system with host ... Used to work before
2.6.31-rc1 with guest net model=e1000 and model=virtio, but with
2.6.31-rc1, only works with model=virtio. .. This could be an
_unrelated_ issue though.

/usr/local/kvm/bin/qemu-system-x86_64 \
        -localtime \
        -net nic,vlan=0,model=e1000 \
        -net tap,script=/root/scripts2/tunx \


Thanks,
Jeff.

OK then your problem is a completely different issue.  Please
strace vpnc and see what it's doing.  You should also take a
tcpdump on the tun interface to go with the strace.
