Re: [Xen-users] Soft Lock on cpu problem Still???

[Xin Chen <xcheney@xxxxxxxxxxxxxx>]

Thanks Pasi,

I downloaded 2.6.18 rpm (because I can't find 12.6.19 one for 
downloading)  kernel-xen and install it then reboot system with this 
kernel version. It seems work now! The system is running for one day 
without crushing. Cheers!
I think I wouldn't install the xensource kernel, it may bring me more 
troubles. For now I just use 2.6.18, until they fix the bugs.
Thanks a lot!!
