Chipset: Intel 865G GMCH Intel ICH5 - 800MHz FSB BIOS Revision: 1007 Embedded LAN : Intel 82562EZ Embedded Graphics: Intel Extreme Graphics 2 RAM 2G 4x512M DDR400 Samsung HDD IDE Seagate Barracuda 120G Processor: P4 - 2.6 GHz HyperThreading OS: Slackware Linux 9.1 Description of the problem: I have installed 2 GB memory 4x512M The embedded video uses system memory. If i set it to use only 1 MB or 32MB of system RAM everything seems ok. The system boots normally and working normally. If i set it to use 4,8 or 16 MB of the system memory the system boots much slower and despite it has no errors or something wrong it works slow. I mean the difference between fast and slow working is really HUGE. I have made the following test: in a 600MB text file replace some text with sed. The line looks like this: sed s/deian/test/g testfile > /dev/null when the system is working normally this is done for ~ 30sec. When the system is working slowly it takes ~ 9 min and 30 sec. I have tested this with kernel 2.4.23 from kernel.org. High memory support is enabled - 4GB. If i have no high memory support enabled the thing are ok but the kernel see only 900MB of my memory. The other strange thing is that with kernel 2.6 the system works normally ONLY IF video card uses 32MB. It is not like with 2.4.23 when 1 and 32M but only with 32MB. I dont think this is normal behavior. And i hope that the problem is not the chipset or hardware. I have searched the news groups and other people has the same problem too but no solution yet. I have attached some logs which may help u find what is wrong. If u need me to do something more just mail me i shall respond as fast as i can. Regards, Deian Chepishev
