[Xen-devel] Kernel BUG at drivers/xen/core/smpboot.c:242
Hi.
I get kernel panic during boot Xen 4.0.1 along with CentOS 5.5 default Xen
kernel (2.6.18.194.el5.xen)
I hooked up a serial connection and it is the output during the boot time:

<0>Kernel panic - not syncing: Fatal exception
(XEN) Domain 0 crashed: rebooting machine in 5 seconds.
Why there is a kernel bug at drivers/xen/core/smpboot.c:242?!!
I am using a Tyan server which has 48 AMD cores and 64GB RAM.
Has anybody got an idea about this bug?!
