Hello, I'm running since some days a recent -HEAD r276659 on an Acer C720 Chromebook which works very nicely and fast (I really have never seen such a fast KDE4 desktop). >From time to time (let's say 2-3 times a day) I see messages like this in /var/log/messages: Jan 16 12:04:24 c720-r276659 kernel: MCA: Bank 0, Status 0x90000040000f0005 Jan 16 12:04:24 c720-r276659 kernel: MCA: Global Cap 0x0000000000000c07, Status 0x0000000000000000 Jan 16 12:04:24 c720-r276659 kernel: MCA: Vendor "GenuineIntel", ID 0x40651, APIC ID 0 Jan 16 12:04:24 c720-r276659 kernel: MCA: CPU 0 COR (1) internal parity error the kernel is: # uname -a FreeBSD c720-r276659 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r276659M: Tue Jan 6 12:55:25 CET 2015 guru@vm-poudriere-r269739:/usr/local/acerC720/obj/usr/local/acerC720/src/sys/GENERIC i386 i.e. the i386 version (because I compile everything in a VM) Are the above messages really a hardware problem?
