Two 3Com 905c-TX NIC's. PFsense maintainer and I have narrowed the issue down to when they enabled CARP in the kernel. I run fine on any FreeBSD 5.3x and 5.4RCx BEFORE they turned on CARP. Once CARP was enabled I get a 100% reproducible panic when accesses the pfsense configuration webGUI. After about 5 seconds into access the webgui through a webrowser, it stops responding and this information is on the screen of the pfsense/FreeBSD based box: --- fatal double fault eip = 0xc046f9b8 esp = 0xc7ab7000 ebp = oxc7ab7014 cpuid = 0; apic id = 00 panic: double fault cpuid = 0 KDB: enter:panic [ thread pid 22 tid 100016 ] stopped at kdb_enter+0x2b:nop >How-To-Repeat: pfsense on my Deskpro, access WebGUI. Started happening after CARP was enabled in the kernel of pfsense builds. >Fix: >Release-Note: >Audit-Trail: >Unformatted: >db --- I am not verse enough to get you more information on my own as I am not a programmer. But I am more than willing to help with any info requested, with help, as this is very easy to reproduce for me. thanks
