Hi Folks,

I'm debugging a driver on a Linux guest using KDB, and while I can do most things, I'm unable to single step. When ever I execute a step (ss or ssb) command the guest enters the blocked state.

I'm running Xen 3.0.2 on a VT enabled i386, host OS is the 2.6.16 kernel that is compiled with 3.0.2, and the guest OS is a stock (except for the KDB patches) 2.6.18

I've not found anything on the net or mail lists to indicate that there is an issue, so any help/guidance would be greatly appreciated!

Thanks!
Pat Thomson
