Re: System freeze (Update, Close to the reason)
X gets kindof restarted for every new session initiated by kdm,
maybe that's locking you off.
If you have some stable LAN anywhere (another NIC) you can find out via ssh
or telnet if only input devices are dead but the kernel is still running.
A real kernel guru will be harder to track...Use grub pre-boot edit mode for
debugging and try pci=routeirq.

This may or may not be related.

(... until "controller restarted")
ok the net driver gets reinitialized ....but why, in first place ?
Are there any other useful logs (daemon.log, syslog) ?

A kernel interrupt problem ?
A typical 2.6.18 SMP irq table before any X launched (textconsole):
CPU0 CPU1
0: 21818 215693 IO-APIC-edge timer
1: 954 0 IO-APIC-edge i8042
9: 108 0 IO-APIC-level acpi
12: 2890 0 IO-APIC-edge i8042
14: 1697 0 IO-APIC-edge ide0
66: 3084 0 PCI-MSI libata
74: 25226 13363 IO-APIC-level ehci_hcd:usb1, uhci_hcd:usb5
82: 107 0 IO-APIC-level uhci_hcd:usb3, HDA Intel
90: 0 0 IO-APIC-level uhci_hcd:usb4
98: 75 0 PCI-MSI eth0

Launching X adds the fglrx (ati) driver:
(...)
169: 12362 0 IO-APIC-level uhci_hcd:usb2, yenta, fglrx
NMI: 0 0
LOC: 554243 554129

As POC you may try to temprarily move /etc/rc2.d/S99kdm out of the way
and start kdm manually (as root, kdm &) at the point where the frereze
uses to occur.
