Unfortunately, my machine is stuck and crashin all the time, worst of all is that it sticks without doing anything, i.e. without having any active application , my pc just stack
,sometimes it gets stuck after login ,and when stack "no leaf is shaken",i can not fix that , very unstable ..
So after seeing that no P9 distribution is working , they reinstalled p8 because I worked with her for three years without any serious problem, however I hope that soon there will be some renewal with corrections,which will make the platform P9 finally stable for my machine.
Update:I found these lines describing the problem
lines 1295 apcupsd[2977]: apcupsd FATAL ERROR in smartsetup.c at line 155
1296 PANIC! Cannot communicate with UPS via serial port.
1297 Please make sure the port specified on the DEVICE directive is correct,
