 I checked your MFC and all the fixes are already included in my patch =
 for 9.1 that we're currently testing with. With that patch, all G8 =
 blades are still running stable and have not shown any more IO stalls. =
 The G7 ones still reliably crash with our test load. So I think we can =
 state that we have already tested wether the changes from head help or =
 not. Is there another reason you want us to test with a stable/9 kernel, =
 or should we stick with the patched 9.1 for now?
 
 In any case I'll apply your DDB hook patch to our patched 9.1 kernel, so =
 we'll get out more debug information when a G7 blade stalls next time.
