It looks like there is an interop problem with a FreeBSD sparc nfs client running from a 4.x i386 nfs server. I got panics about once a day on my nfs server at home when I tried to do sparc package builds from it (this is with RELENG_4 going back at least 6 months), and in the past two days (since I started using it to build sparc packages too) bento.freebsd.org has panicked twice with:
Fatal double fault: eip = 0xc0279bf6 esp = 0xe1771fec ebp = 0xe1772018 mp_lock = 00000100; cpuid = 0; lapic.id = 01000000 panic: double fault mp_lock = 00000100; cpuid = 0; lapic.id = 01000000 boot() called on cpu#0 Since I switched to a 5.0 nfs server at home I have not seen this problem, so it appears to be RELENG_4 only. Has anyone else experienced this? Kris
