Kernel Error with i845G

Kernel Error with i845G

[Janek Neubert]

Hi,

i have a bought an EPOX board (4G4A+) with Intel i845G chipset. While i was 
trying a 2.4.18 kernel, the machine stops after "Ok, booting the kernel ...". I 
have to use the lilo command mem=<memory without shared graphic ram>M in 
megabytes. All kernels newer than 2.4.3 cause this error. Since version 2.4.19, 
this solution is unusable. I think, this is a kernel problem, because i know 
from other people having the same problem, but other boards with i845G. I need 
the 2.4.19 to use my HPT372. Please help and finf the error.

I think the problem is a failure in the routine getting the size of memory from 
BIOS. Linux thinks, i have 640k!!! RAM. Only the mem-parameter can solve it.

Thx

I have some more informations for you:

dmesg - output with mem=248M

Someone told me to post the output from the serial port. Sorry, i have used
minicom, cat and a null modem cabel, but there's no output.

When I use 256MB RAM, all works fine with mem=248M, if i use 512MB RAM and 
mem=504M, the maschine crashs after a full memory use like compiling a kernel.

Thx
