Description D. Hugh Redelmeier 2001-03-19 13:48:04 EST
startx fails on Intel 810 system with message
	(EE) I810(0): Not enough memory for dma buffers

Motherboard is MSI 6183 version 1 (not 6183E) with 64M of RAM.
System is full RHL7 install, with updates as of end of 2001 February.

- tried to boot with "mem=56m", but made no difference
- tried with both 2.2.17-14 and 2.2.16-22 kernels -- no difference.

From a 2.2.17-14 kernel boot:
	Linux agpgart interface v0.99 (c) Jeff Hartmann
	agpgart: Maximum main memory to use for agp memory: 22M
	agpgart: Detected an Intel i810 DC100 Chipset.
	agpgart: detected 4MB dedicated video ram.
	agpgart: AGP aperture is 64M @ 0xe8000000
From a startx log:
	(--) I810(0): Chipset: "i810-dc100"
	(--) I810(0): Linear framebuffer at 0xE8000000
	(--) I810(0): IO registers at addr 0xEFF80000

	(II) I810(0): Buffer map : 0
	(EE) I810(0): Not enough memory for dma buffers
	(0): [drm] failed to remove DRM signal handler

	Fatal server error:

I have more log info saved, but it seems too large for this margin.

I forgot to mention that 
is interesting, but out of date.  Xfree4 is different from Xfree3 and the
kernels has advanced in 810 support too.  But I think that there still are
issues with 810 support, so a new version would be welcome.
Comment 2 Mike A. Harris 2001-03-22 15:17:52 EST
In order to look into this problem I require a full copy of your XFree86
config file, and a full X server log.  Please attach them using the file

I just did an upgrade-install to RHL7.1.  startx works just fine.  Still no idea
what the problem was, but it looks like I'm not going to be the one to figure it
Comment 7 Mike A. Harris 2001-06-12 02:48:54 EDT
Ok glad to hear it works for you.  Also, there are some other known
problems with the 7.1 X server that have been fixed in 4.0.3-21, and
will be released on my ftp space shortly:
