Comment (by kallisti5):
I purchased a PineView netbook of this generation, looks like the pll
calculation is busted:
{{{
KERN: intel_extreme: IsConnected: LVDS C PortRegister: 0x5001180
KERN: intel_extreme: CALLED virtual status_t
LVDSPort::SetDisplayMode(display_mode*, uint32)
KERN: intel_extreme: SetDisplayMode: LVDS C-3 1024x600
KERN: intel_extreme: SetDisplayMode: hardware mode will actually be
1024x600 (unscaled)
KERN: intel_extreme: PLL limits, min: p 7 (p1 1, p2 14), n 1, m 70 (m1 8,
m2 3)
KERN: intel_extreme: PLL limits, max: p 98 (p1 8, p2 7), n 6, m 120 (m1
18, m2 7)
KERN: intel_extreme: compute_pll_divisors: required MHz: 49.8
KERN: intel_extreme: compute_pll_divisors: found: inf MHz, p = 0 (p1 = 0,
p2 = 344), n = 0, m = 600 (m1 = 2, m2 = -450708296)
KERN: intel_extreme: LVDS: dual channel
}}}
I'll take a gander.
