I just put together a machine with a 3GHz Athlon, 1Gb of 400MHz
DDR-RAM and a 64 Mb dual-head ATI Radeon 7500 PCI. It's running
a Debian 2.6.6-k7 kernel. The system works fine and seems pretty
performant, but every now and then it does weird things.
For instance, when I enter an OpenOffice.org document with the
mouse, or when I open various images in rapid succession in firefox
as tabs, then the mouse jerks and xmms or ogg123 cuts out.
It all peaks when I fullsize a 2000x1700 pixel image across the
Xinerama screens. The system basically becomes unresponsive for
a couple of seconds. I have 1.2 GHz Athlons with 256Mb that handle
this just fine.
There is nothing logged to kern.log or any other log, so I assume
ths system is healthy.
So my question is where this is coming from. I am not even sure
where to start looking. Would someone here be able to offer some
advice?
Here are the relevant lspci entries:
0000:00:00.0 Host bridge: VIA Technologies, Inc. VT8377 [KT400/KT600 AGP] Host Bridge
0000:00:01.0 PCI bridge: VIA Technologies, Inc. VT8235 PCI Bridge
0000:00:0b.0 VGA compatible controller: ATI Technologies Inc Radeon RV200 QW [Radeon 7500]
0000:00:11.0 ISA bridge: VIA Technologies, Inc. VT8235 ISA Bridge
0000:00:11.1 IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 06)
The system is using APIC, the local APIC is enabled, IO-APIC works
too.
Where to look?
Thanks,
