Yeah its a complete bitch to get stable. I fully agree with Cameron.
Most stablist combo I found (infact the only combo that is remotely bareable is):
0823 Baseband with 0823 (V21F Canada) RIL
CyanogenMod 7.2 RC
Standard Cyanogenmod Kernel
Thats on my P990, Vodafone, UK
Any other baseband causes the phone to randomly black screen of death
Any other ROM the alarm doesnt go off when it should (still happens now but not nearly as often)
Wont be going anywhere near anything LG ever again, as much as I love tinkering, I expect the piece of crap to at least 'work' out the box.
I could have another huge rant now about technology going backwards but ill do you all a favour
