Hi Maacruz, I'm running the kernel from May. I haven't noticed the reboot issue, but I'm currently only getting around 6 days use on a charge (it really depends on usage) and then I shutdown to swap-out the battery with a fully charged one anyway. Since loading the May kernel though I haven't had one instance of the shutdown issue, so I am somewhat reluctant to rollback to the March kernel if that means I could start experiencing the shutdown issue again. Is there any other reason why I wouldn't want to stay on the May kernel? I'll try and start tracking my uptime a little more carefully to see if the restart issue is affecting me and I'm not aware of it. Overall I have been completely happy with the May kernel. Thanks!!
