Hi Im having a very similar problem as the one reported in Bug Query 5374. Im trying to solve the problem but Im finding it very hard to even get started. Is there somewhere besides the code that I can start to try and understand how SMP is being handled?
http://cvs.openbsd.org/cgi-bin/query-pr-wrapper?full=yes&numbers=5374 I can usually duplicate the crash by running the follwing script several times concurrently. #!/usr/bin/perl system("tcpdump -i em1 -w /var/crashTest1.pcap&"); system("tcpdump -i em1 -w /var/crashTest2.pcap&"); system("tcpdump -i em1 -w /var/crashTest3.pcap&"); system("tcpdump -i em1 -w /var/crashTest4.pcap&"); system("tcpdump -i em1 -w /var/crashTest5.pcap&"); system("tcpdump -i em1 -w /var/crashTest6.pcap&"); system("tcpdump -i em1 -w /var/crashTest7.pcap&"); while (1) { system("nmap 192.168.66.90&"); } Then after about an hour, when you try and reboot, I get an error: uvm_fault(0x..., 0x..., 0, 1) -> e kernel: page fault trap, code = 0 stopped at pmap_page_remove_86+0x114: 0(%eax, %edx, 4), %eax The trace output is: pmap_page_remove_86(d0d31420,c0,e9b57e2c,d04adeb9,e99f) at pmap_page_remove_86+0x114 uvm_vnp_terminate(d8034e04,0,0,0,0,14,0,d7e95004) at uvm_vnpterminate+0x31f uvm_attach(d8034e04,0,2,0,d7f38378) at uvn_attach+0x2b5 uvm_unmap_detach(d7e959a4,0,d7f3841c,1) at uvm_unmap_detach+-x62 uvmspace_free(d7f38378,6,d08120e0) at uvmspace_free+0xfd uvm_exit(d7fbb868,14,8,286) at uvm_exit+0x19 reaper(d80df430) at reaper+0x90 Bad frame pointer: 0xd0913eb8 A couple times the error has also occured on its own without saying 'reboot' when running a ton of nmaps and tcpdumps at the same time. This trace is remarkably similar to the one in Bug Query 5374. Additionally I am using the same processor as he is. There is an unkown core statement in my dmesg but both cores seem to be working correctly. Here is my dmesg: OpenBSD 4.0 (GENERIC.MP) #936: Sat Sep 16 19:27:28 MDT 2006 [EMAIL PROTECTED]:/usr/src/sys/arch/i386/compile/GENERIC.MP cpu0: Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz ("GenuineIntel"
