Kernel panics (a lot!) in 10.2.4

[Evert Smit]

Dera List,

Since upgrading to 10.2.4 I experience a lot of kernel paics, at least,
those events wher the screen slowly from top to bottom becomes darker and a
text in English, German, Japanese etcetera appears telling me I must
restart. This happens most often when ... I want to restart. It almost looks
like a hardware conflict, but I didn'd add new hardware since upgrading.
Re-applying the 10.2.4 updater (the combo) and in OpenFirmware do a
reset-all doesn't help. I somehow fear it is a USB related thing, a failure
to close a port or so. Anyone seen this before?

The machine is a G4 450 MP, 2 GB RAM, 80 + 30 + 120 + 120 GB HD's (last two
through an Acard ATA133 PCI), PCI FireWire/USB2 combo card, and ATI Radeon
8560 driving 2 LCD's. Mouse is a Logitech MX 700. Furthermore 2 USB Hubs,
iMic, Scanners (Flatbed USB and FireWire Film), USB Printer and Ethernet
printer, Palm USB Cradle and FireWire 24x CD-RW. Internet via Ethernet to a
Linux Router. I know, a lot of stuff...
