Listmates,
For all those that relay on the ATI fglrx driver, Be Aware that the ATI
fglrx driver will not compile against the new 2.6.23 kernel. This is an
ATI problem and not a kernel issue. Several bug reports have already
been filed. See:
http://ati.cchtml.com/show_bug.cgi?id=803
This evening, a new patch was posted to the ati.cchtml.com site. I have
NOT tested this patch yet, but I can confirm that without it the driver
post-install script that builds the fglrx.ko kernel module will FAIL.
Hopefully this will spare others the surprise that comes from the result:
******************************
Build of kernel module failed!
