I installed 2.2 Release a couple days ago and then noticed it was
interfering with my utterly unconnected radio on the other end of my
desk.
That's some nontrivial EM interference, so I figured generating it CAN'T
be doing good things to my system.
Everything runs fine, but, just after booting and probing stops, my
radio starts registering interference pulses at about 3.75 Hz which
continue until I reboot. These pulses are about the same volume as
normal radio programs.
I've also got Win95 on the machine, and I've never encountered anything
like this (there's always boot-time interference, but then it stops).
The interference is the same whether the radio is plugged into the same
power bar/socket (as the computer) or not.
It doesn't seem to be the monitor, speakers, mouse, or keyboard (cold
booted with those disconnected from computer and power and got same
result).
I've got a P133 in a P/I-P55T2P4 motherboard, SB32, Matrox Milennium,
CNet 650E Plus ethernet card, Toshiba XM-series 6X CD-ROM, 3.5" floppy
drive, Quantum 3.2 GB Fireball and Western Digital 2.1 GB (both EIDE),
and a Mag DX17T monitor. I've appended my boot messages to the end of
this post (on the advice of another FreeBSD user) in case those are
useful. The interference pulses start just after the last of these
messages.
Anyone have ANY idea what's going on?
Thnks in advance.
