[ltp] RH-7.3 on thinkpad X30?

13 Jul 2003 12:17:28 -0700

Ok, finally got a chance to play with this a bit.  Exec summary:

- Thinkpad X30 (has Intel 830 graphics chipset)
- Running RedHat-7.3 (company-mandated linux release)
- Issues w/ X crashing when suspend/resume of the laptop
- Partially resolved by installing 2.4.20-18.7 kernel (RedHat errata
kernel release) and "home-brew" XFree86-4.3
- Still see occasional Xserver crashes

Slightly more detail...

Installed the above-mentioned kernel, both binary and source, but so far
haven't config'd and built a "custom" kernel yet (troll: anybody got a
decent kernel config for an X30?)

The XFree86-4.3 comes from RedHat source RPM (XFree86-4.3.0-2.src.rpm,
and another troll: anyone know of a more current RPM source-ball for
XFree86-4.3?).

The XFree86-4.3 was built via "rpmbuild", but was not built on the X30. 
It was built on my desktop, which is running the same RedHat-7.3
environment *except* for the fact that the desktop is still running
2.4.18-27.7 kernel.

Where I still have problems... the X server does occasionally crash. 
About once every 6 to 10 resume's the X server will crash.  Furthermore,
I can force the X server to crash by trying to switch to an alternate
(text) console (e.g., "ALT-CTL-F2").  In both cases, these messages
appear in /var/log/messages:

Then, in the end of /var/log/XFree86.0.log:

Fatal server error:

And, of course, the X server restarts.

Can anybody toss me any clues on this?  It looks like an X/DRM issue?
