Total Random Freeze

my fresh arch install randomly freezes very often (never makes it longer than 30 min). the freeze is total, cant ssh in and the sysrq key is the dead. Nothing is outputted in the logs for the time of the freeze even with debug. the freeze seams to occur more often when downloading something through pacman or when watching flash video making me suspect the network connection (the pc is connected though lan). the pc is perfectly stable in windows vista and was stable in PCLOS (i installed arch over pclos).


I also have a Laptop with an arch install wish has recently had the same issues (freeze nothing in the logs no sysrq), but much less often.


the desktop has a amd phenomen II 940 cpu and a hd radeon 5850 gpu (using the open source ati driver and KMS).

About the LAN card:

02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)
        Subsystem: Giga-byte Technology GA-EP45-DS5 Motherboard
        Flags: bus master, fast devsel, latency 0, IRQ 43
        I/O ports at de00 [size=256]
        Memory at fdbff000 (64-bit, prefetchable) [size=4K]
        Memory at fdbe0000 (64-bit, prefetchable) [size=64K]
        [virtual] Expansion ROM at fdb00000 [disabled] [size=64K]
        Capabilities: <access denied>
        Kernel driver in use: r8169
        Kernel modules: r8169

The laptop is an eeepc 1215b, with a amd  e-350 cpu, and a hd 6170 gpu (using FGLRX).


Im really at a loss of how to debug this (both pcs have no com port), ill run memtest86+ later today, but I doubt that the RAM is at fault here

Re: Total Random Freeze

I had problems with this card and the r8169 kernel module, too. Try the module r8168 from AUR. It solved it for me.
To make it permanent, blacklist the module with

echo "blacklist r8169" >> /etc/modprobe.d/modprobe.conf

To load the r8168 module on boot, add it to the MODULES list in your /etc/rc.conf file and reboot.

Re: Total Random Freeze

That didnt help, but disabeling KMS (or installing FGLRX) worked
