Re: [ROM] CM7.2 Port for Optimus S by thekraven 2/7/2012 zvd only
With this ROM, the battery drains extremely quickly with bluetooth turned on. Using the better battery stats app I have seen that a kernel wakelock called "msm_serial_hs_dma" is not allowing the phone to sleep when bluetooth is turned on. I found a forum post about this bug on a different phone on xda here which says that this issue is "the UART clock is never disabled" and reading the thread further it appears that they eventually fixed the bug. Hopefully this information will be of help to thekraven for this rom. That link also has a link to code changes which I think fixed the bug. A different handset, but hopefully will be relevent to the optimus s.
I have tried different kernels with this ROM and the bug persists.
I have attached screenshots of the wakelock screen from betterbatterystats showing the msm_serial_hs_dma wakelock and one showing how the phone is awake 100% of the time bluetooth is enabled.
Also, the same bug exists in the cold-as-ice ZVD CM9 port.
