Hi,
I am porting my 10 gig network driver to solaris( gldv3 base ) . Everything
seems to be fine until this crash happens , this is after a one hour of TCP
traffic between the network interface and a client .
panic[cpu1]/thread=fffffe8000425c80:
BAD TRAP: type=e (#pf Page fault) rp=fffffe8000425820 addr=4300000c occurred in
module "mac_ether" due to an illegal access to a user address
sched:

Where osm_process_sts is my interrupt function . I tried to debug using
mdb but iam clueless.
Iam using
uname -a
SunOS unknown 5.10 Generic_120012-14 i86pc i386 i86pc
Solaris 10 8/07 s10x_u4wos_12b X86
Solaris 08/07..
