Bug#525900: xorg 1:7.3+1 crashes on SPARC, system not responsive any more
Package: xorg
Version: Version: 1:7.3+18
Severity: important
Debian SPARC xorg crashes my Ultra10 on startup (service gdm) or when I
try to start X manually. The system becomes unresponsive. This happens
regardless of the driver chosen in xorg.conf. This was not the case with
the former version in Debian 5.0 which used to work fine.
Probable reason and fix (taken from http://kristof.willen.be/node/689):
The code in Xorg was trying to mimmick VGA routing by disabling I/O
responses behind the Simba PCI controller. Unfortunately, doing this
also happens to disable access to the IDE controller I/O registers, thus
crashing the system. No console messages because the console has been
put into framebuffer mode by the X server already.
In the xorg log this is the error displayed before the crash :
xf86MapPciMem: Could not mmap PCI memory
Inappropiate ioctl for device
Kind regards
