X log from crash

xserver (v 1.4.0.90-r3 from portage) crashes on startup using xf86-video-ati from git.

Specs:
HP Alphaserver DS20L (dual 833 MHz EV68s)
Radeon X1550 PCI (RV516)

gdb reveals the crash occurs in atombios_dac_detect in radeon_drv.so.

Sounds like alpha may need an alternate pragma pack.  See bug 14594.

Try removing the following lines from configure.ac:

case $host_os in
*linux*)
AC_DEFINE(FGL_LINUX, 1, [Use linux pragma pack]) ;;
esac

then re-run autogen.sh and rebuild.
Comment 2 Alex Deucher 2008-04-16 01:27:47 UTC 
Nevermind the previous comment.  The driver is not able to access the bios.
Comment 3 Matt Turner 2008-04-17 10:26:32 UTC 
I filed this bug (https://bugs.freedesktop.org/show_bug.cgi?id=15521) for the same problem with radeonhd. I assume the fix applied to radeonhd would be similar to the one needed here.

What information can I provide to assist in fixing this bug?

The server needs to be fixed to properly read the rom on alpha architectures.

Kernel bug. Closing.
