[Xen-users] Soft Lockup Bug Fixed Yet?

[Simon Capstick <simon@xxxxxxxxxxxxxxxx>]

Hi,

I upgraded to Xen 3.0.3 a month or so ago hoping to eliminate the soft 
lock-up bug on a production server (dual single-core Opterons).  However 
I'm still getting about one a week in a DomU, seemingly during heavy IO. 
 Does anyone know if this has been fixed in 3.0.4?
Regards,

Simon
