Yes! From dmesg:

cpu0 at mainbus0: (uniprocessor)
cpu0: AMD Unknown K7 (Athlon) (686-class), 1799.90 MHz, id 0x10ff0
cpu0: features 78bfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR>
cpu0: features 78bfbff<PGE,MCA,CMOV,PAT,PSE36,MPC,MMX>
cpu0: features 78bfbff<FXSR,SSE,SSE2>
cpu0: "AMD Athlon(tm) 64 Processor 3000+"

I am using NetBSD/i386.


I get a similar error even when sofdeps are off, but quotas 
are on. It seems to be nearly reproduceable, I just have to 
unpack a large tar file.


Maybe we can solve this thing?
