pc_efi & Bluetooth hassles [when overclocked]

[shoarthing]

At any overclocked fsb, the connection between my Apple bluetooth keyboard/mouse & either of my USB Bluetooth dongles (tried both 'Apple-approved' D-Link DBT-120 versions b4 & C1) malfunction inside Leopard; but not inside ordinary Darwin-boot Tiger. Leopard becomes unusable.

 

Symptoms are: 1st - cannot select a menu by a mouse-click; 2nd - any text-entry box recently typed in gathers a row of 'ghost' full-stops; 3rd - mouse-pointer starts to flicker . . by then the system is unusuable & has to be shut down.

 

A restart sees the same symptoms immediately, a shutdown sees them within a few minutes.

 

It is *not* a hardware issue: have used 4 known-working firmwares for this P5WDH.

 

Applies to pc_efi versions 1>v5 (plus Uphuck's 'magic boot' '200MHz' & a v1 netkas modded to 400MHz by gotoh).

 

Used vanilla SMBIOS & 4 recent netkas versions. Kernel is vanilla 10.5.1 (the major point of running pc_efi)

 

. . . no issues at default FSB of my e6420 (266).

 

Anyone here with similar firsthand experiences or a diagnosis?
