2.4.25: kfree_skb on hard IRQ during ISDN dialin

[Andreas Steinmetz]

Im getting this kernel warning during ISDN dialins:

Apr 10 22:24:28 titanic pppd[895]: local  IP address 10.1.1.7
Apr 10 22:24:28 titanic pppd[895]: remote IP address 10.1.1.8
Apr 10 22:25:31 titanic kernel: Warning: kfree_skb on hard IRQ c022d0a0
Apr 10 22:25:34 titanic last message repeated 2 times
Apr 10 22:26:20 titanic pppd[895]: Modem hangup
Apr 10 22:26:20 titanic pppd[895]: Connection terminated.

The client of the dialin is a Nokia 6820. It doesn't seem that this 
warning causes any real trouble as the system otherwise continues to 
work normally. I don't know if this warning is ISDN or PPP related.

System:

Tyan Tomcat K8S (S2850) with Opteron 144 runing in 32 bit mode
