Category: intel Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Shawn starr (sh0nx) Assigned to: Nobody/Anonymous (nobody) Summary: Soft lockups when installing RHEL5 over PXE Initial Comment: CPU Type: ========= Family: 15 Model: 6 Stepping: 2 model name: Intel(R) Pentium(R) D CPU 3.00GHz This CPU has VT extensions Steps to reproduce (you may need to retry a few times to trigger this to fail) 1) Try to install RHEL 5.1 64bit guest with a PXE installation. Not using any virtio drivers. 2) Sometimes when trying to format a disk CPU gets stuck, install hangs but the vm is still responsive to control (reboot, etc) 3) I have a 32bit Windows XP VM running also with kvm * Note: If it doesn't soft lockup, on reboot into the newly installed VM, ssh-keygen segfaults (this has happened 3 times). KVM version: (kvm 75 snapshot) [ 1489.698357] loaded kvm module (kvm-snapshot-20080909) RHEL5 64bit GUEST Crash Output: =============================== <3>BUG: soft lockup - CPU#0 stuck for 10s!
