RE: [Xen-ia64-devel] Create 2nd XenU fail after destroy 1st one

[Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>]

Hi, Yongkang and all

I have reproduced your problem.
Hmm... I look like this fault is occurred at srlz instruction.
I try to debug it.

# Do everyone think xen's printf is buggy?

My environment:
Machine : Tiger4
OS      : RHEL4 Update2
gestOS  : RHEL4 Update2

How to reproduce
1. xend start
2. xm create domU
3. xm console domU
   -> and hit poweroff command.
4. xm create domU
   then call trace is happend in xm dmesg.
   
5. xm destroy domU
   -> then system hang up...

Best Regards,

Akio Takebe
