>Description:
Hi,

I am trying to install NetBSD-7.99.18-amd64 on a small computer. During the booting the kernel drops into the debugger:

uvm_fault(0xffffffff811e260, 0x0, 1) -> e
fatal page fault in supervisor mode
trap type 6 code 0 rip ffffffff805445e4 cs 8 rflags 10286 cr2 f0 i level 0 rsp fffffe810e1f3e50
curlwp 0xfffffe810e1ee9a0 pid 0.35 lowest kstack 0xfffffe810e1f02c0
kernel: page fault trap, code=0
Stopped in pid 0.35  (system) at netbsd:intel_gen6_powersave_work+0x430: move  f
0(%rdx),%rdx
db{3}>

The system is frozen at this point. No keyboard interaction is possible. 





>How-To-Repeat:
It happens always. Boot options 2 & 3 didn't works too.
