out of swap on shutdown
On shutdown, on machines with a large tmpfs which has been thrashed, I see: UVM: pid 1029.1 (master), uid 0 killed: out of swap UVM: pid 701.1 (qmgr), uid 12 killed: out of swap with what appears as a hang. In the past, I have left a box in this state overnight with no change. (I think about a year ago this would panic instead.) The difference is that today I just happen to have a serial console plugged in. Box running yesterday's -current/amd64.

Re: More amd64 drmkms radeon
Mine is also much better now - DRMKMS kernel boots into multiuser, switches the mode and works fine in multiuser. Xorg doesn't start; it blanks the screen and I presume panics, but I can't see anything; I will have to switch to serial console to see what is going on (I also had a panic from a KASSERT in igmp.c, which did panic on every shutdown/reboot/halt, but I commented it out and now it reboots cleanly).

I am not sure about this recent addition, you might have a contaminated objdir, do you start from empty dir? I am thinking about this setup you are trying for.. Firstly, if GCC is being used to build something, then I think that it will always add -lgcc to the linker command. This is because it uses that to provide support for specific features (the code it produces calls routines in there to do things, such as floating point math) Then, in lib/Makefile, we don't build libgcc if MKGCC==no but perhaps we should (if ACTIVE_CC==gcc then it will be needed during the build if not the runtime) if you force libgcc to be built (comment out the MKGCC conditional in lib/Makefile) will it continue? also, you should probably use HAVE_GCC=48 since that is the version in use, and the version number is checked sometimes for various features iain
