XFree86 vs. 2.5.54 - reboot
This probably applies to immediately prior kernels in the 2.5 series as well. 2.5.54 seemed like a good time to jump in and test the waters, so to speak...
AMD K6-III 450 running a 2.4.19 kernel with vesafb, XFree86 4.1.0, and a USB mouse works fine. Same setup with a 2.5.54 kernel does a cold reboot when I type "startx". In both cases, the initial video state is "vga=791" as set in /etc/lilo.conf. As far as the crash, there's no debug output of any kind in the logs to help narrow down the cause.
As best I can remember, the last time I had everything kinda working with a 2.5.X kernel was prior to the introduction of the new module-init tools. This isn't a jab at Rusty et. al. I'm merely trying to come up with an approximate timeframe during which something changed which is causing the problem. The recent framebuffer driver changes probably have something to with this issue.
If this is a known problem, would someone be kind enough to summarize the discussion or let me know approximately when the discussion took place so I can dig for it in the linux-kernel archives? Thanks!

Hi,
I've got the same probelm with my K6-III 450, too...
The last version I tested was 2.5.52 and it worked perfektly... But now with 2.5.54 (I did not test 2.5.53) when the 'nvidia' module is used (loading it works with no problems...) the Computer reboots... If I do not use this module X works...
There seems to be a problem with an other module, too...
'nfsd' is ok to load, but when a remote machine tries to mount a directory a reboot occures, too...
I do not know if there is a problem with other modules, if I will find any I will report them here...

I saw exactly the same. In my case it appears to be due to miscompilation of a particular sysenter patch which went into 2.5.53. If you're using gcc-2.91.66 (aka `kgcc') then try 2.95.x instead.

I'm running gcc-2.95.3 here. Is that a "sufficiently correct" version to avoid the miscompilation problem?

Yup. It must be something else then. Perhaps you should try disabling various DRM/AGP type things in config, see if that helps. If not, it would help if you could identify the kernel version at which the failure started to occur.

All the DRM/AGP stuff was configured as modules, and none of them were loaded prior to running "startx". If disabling them entirely is different from not loading them, I'll be happy to give that a try.

Wish I knew for certain... The 2.5 series got to be unusable from my perspective somewhere in the 2.5.50 timeframe. 2.5.51 may have worked:
that was the last 2.5 kernel I built prior to 2.5.54. I didn't run it as a "production" kernel either because of the X11 problem, or because the ALSA emu10k1 driver was broken (the latter is fine in 2.5.54 as far as I can tell).
2.5.55 is out. Maybe I should give that a try.

2.5.55 appears to work fine with CONFIG_AGP and CONFIG_DRM undefined. I'll retry with CONFIG_AGP_MODULE next...

Can you send me lspci output, and agp related msgs from dmesg.

Final (?) report: with 2.5.56 and all the AGP/DRM modules configured and built (that I normally configure and build), no problems that I can tell. Whatever it was, it probably got fixed in 2.5.55.
