I got an attack of the network lags after upgrading to 0.99 
Downgrading didn't help, powering down, restarting and rebooting didn't help. Even with cgminer not running ping times can take up to 2 seconds. SSH'ing in is excruciatingly slow. One time I couldn't even ssh in until I restarted it again. I just barely got it mining again. I saw others had gremlins that went away, but I can't seem to find any way to repair it.

also this!
sad to be glad that someone who knows how to fix these issues is also suffering...
i would've requested an RMA already had i any confidence it would be quick and effective
i do not
@bogart - do you have any close ups of the areas you advised checking for 'opens' around the VRMs??
if there is an obvious error that can be fixed in a jiffy it may help the 'few' who still struggle to get anywhere near the 550 - 560
im fortunate to be stable at 529.8 and unwilling to send it back to maybe get a worse module sent back - for now.
@ phoenix below - yes, we know! you may have mentioned that
as you seem to have taken into account - not all posts get the recognition they deserve. (and therefore require pea-roasting)
