Hello,
I have just installed 2.6.31 (from opensuse 11.2) one a tulip-equipped computer and I get the following error message from the kernel :

This comes from a BUG_ON in napi_enable in netdevice.h.
napi_enable itself is called by tulip_up as such :
#ifdef CONFIG_TULIP_NAPI napi_enable(&tp->napi); #endif
At first reading, a matching napi_disable is called in tulip_down.
Does someone know what could be wrong and have a fix or should I look myself ?
Thanks in advance
Philippe
