Linux Boot problems with 640 Megs + Memory
Hi All
I am new to the forum, but I have a RH 8.0 problem that I am hoping someone can help me with.
I am trying to set up Linux with 2 Gigs of RAM, and to increase the VMALLOC space from the default 128 Megs to 256 Megs. The system that I am building is for a Video Editing solution that works with HD resolution Video. Because of this we need to run a powerful graphics card. We are currently using the NVIDEA FX 2000 card, and planning to move to the FX 3000 in the near future.
Our application also has a proprietary File System, which also loads into VMALLOC space. With the FX 2000 card loaded, it eats up a big portion of the VLAMMOC space, and therefore really limits us to the size of File system we can create.
So to get around this I tried to edit the VMALLOC line in the page.h file, and recompile the kernel. The compile seemed to be successful, but when I reboot I get the following errors.
VFS: Cannot open root device "LABEL=/" or 00:00
Please append a corret "root"= boot option
Kernel panic: VFS: Unable to mount root FS on 00:00
This would lead me to believe that it cannot find the boot drive on the scsi chain, but in fact if I edit the grub line and add mem=640m it boot fine. Anything above 640m, and the system hangs at boot with the same error as above.
Any help would be greatly appreciated.
System details
IBM 6221 dual 3.06 GHZ processors
2 Gigs of RAM
RH 8.0
Kernel version 2.4.18-14smp
Thanks in Advance
