Re: 12.0-ALPHA6 dumps with 'Fatal double fault'
Port is devel/apr1 and platform is amd64. Works fine on my side. It would be helpful if you could build a kernel with debug symbols, reproduce the problem and provide a stack strace. Unfortunately I cannot. It is a production machine without debug that does not like to run on 11.1 OR 11.2 for some strange reason [1]. And I really do not I'm not referring to 11.1 or 11.2. Just the kernel you use with debug symbols. I know, this was only some background information. want to run it on 11.0 anymore. Perhaps it is some crappy hardware from our hoster, I don't know. Anyway, after minimal-updating SVN to very-latest and removing SCTP it behaves just fine under load. Removing SCTP means removing it from the kernel or disabling it in the port? From the kernel. I commented out 'options SCTP' and recompiled. Since you said that it crashed multiple times makes me wonder if this problem is related to SCTP in particular or if there is some other generic issue... The mentioned commit [2] lies exactly in my SVN update delta. So this could be the reason, too(?) Sadly I am to busy right now to investigate further, sorry. OK. If you have some spare time, enable SCTP again and see if the problem is related to it... Yes, if time and point in time permits, because that's a production server and I can only mess around with it late night.

Re: 12.0-ALPHA6 dumps with 'Fatal double fault'
Can you elaborate which port was triggering the fault and which platform you are using? I would like to reproduce the issue and fix it. Port is devel/apr1 and platform is amd64. CPU: Intel(R) Xeon(R) CPU E31245 @ 3.30GHz (3300.10-MHz K8-class CPU) Origin="GenuineIntel" Id=0x206a7 Family=0x6 Model=0x2a Stepping=7 Features=0xbfebfbff Features2=0x1fbae3ff AMD Features=0x28100800 AMD Features2=0x1 XSAVE Features=0x1 VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID TSC: P-state invariant, performance statistics It crashed multiple times randomly under heavy load when compiling ports. But I observed a crash two times exactly in the same place: configure script SCTP test in devel/apr1.

Re: 12.0-ALPHA6 dumps with 'Fatal double fault'
I removed SCTP from kernel and updated from r338797 to r338827 and the problem seems to be gone.
