What's more is Kai says he's running 5.3 but the fix should be in that
kernel. What I do wonder is if when the centos kernel was built, was it
included? Maybe the CentOS Kernel builder could let us know?
2.6.19-rc3 and higher are supposed to have the fix?
It is however a strange thing when you encounter it. I pulled my hair
for a long time.
Last thing is he has this problem on a R200 and from memory those were
not a problem. Could be this is something new? He could check for a BIOS
Revision if there is one.
