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: #pf Page fault Bad kernel fault at addr=0x4300000c pid=0, pc=0xfffffffff3dbace5, sp=0xfffffe8000425910, eflags=0x10216 cr0: 8005003b<pg,wp,ne,et,ts,mp,pe> cr4: 6f0<xmme,fxsr,pge,mce,pae,pse> cr2: 4300000c cr3: 68fe000 cr8: c rdi: ffffffff85bf63c0 rsi: 0 rdx: 43000006 rcx: ffffffff85bf63c0 r8: fffffe8000425a6c r9: 1 rax: 5ea rbx: fffffe8000425a70 rbp: fffffe8000425920 r10: ffffffff8bdb1a00 r11: 0 r12: 43000000 r13: 1 r14: fffffe8000425a6a r15: ffffffff85bf63c0 fsb: ffffffff80000000 gsb: ffffffff81432800 ds: 43 es: 43 fs: 0 gs: 1c3 trp: e err: 0 rip: fffffffff3dbace5 cs: 28 rfl: 10216 rsp: fffffe8000425910 ss: 30 fffffe8000425730 unix:die+da () fffffe8000425810 unix:trap+d86 () fffffe8000425820 unix:cmntrap+13f () fffffe8000425920 mac_ether:mac_ether_header_info+25 () fffffe8000425930 mac:mac_header_info+15 () fffffe8000425970 dls:dls_link_header_info+45 () fffffe8000425a10 dls:i_dls_link_subchain+38 () fffffe8000425ad0 dls:i_dls_link_rx+59 () fffffe8000425b00 mac:mac_rx+45 () fffffe8000425b70 benet:process_nic_rx_completion+3f7 () fffffe8000425bc0 benet:process_ucast_rx_completion+cf () fffffe8000425c20 benet:osm_process_sts+141 () fffffe8000425c60 unix:av_dispatch_softvect+62 () fffffe8000425c70 unix:intr_thread+a5 () Where osm_process_sts is my interrupt function .
