[Qemu-devel] [Bug 1011142] Re: Arm emulation do a crash

[BRULE Herman]

Because it stop on:
Program received signal SIG38, Real-time event 38.
[Switching to Thread 0x7ffff1125700 (LWP 32348)]

Same with the ulimit:

debian6-19-04-2012.img -m 256 -append "root=/dev/sda2 loglevel=7 debug" -serial 
stdio -no-kvm

For whole my system:

The bt for other program crash work.

Title:
  Arm emulation do a crash

Status in QEMU:
  New

Bug description:
  Hello, I have try multiple image for the raspberry pi, with this cli:
  /usr/bin/qemu-system-arm -kernel kernel-rasptoo -M versatilepb -cpu arm1176 
-hda hdd.img -m 256 -append "root=/dev/sda2 loglevel=7 debug" -serial stdio 
-no-kvm
  I don't know why, with kvm it say:
  KVM not supported for this target
  No accelerator found!

  I can't debug it with gdb, it crash after the kernel boot (the qemu 
application crash).
  I'm under gentoo:
  [ebuild   R   ~] app-emulation/qemu-kvm-1.0.1-r1  USE="aio alsa curl ncurses
