Hi, I have two very similar AMD based work stations running fully current CentOS x86_64. Both have 4Gb of RAM, both have
[rkampen@media ~]$ sudo rpm -qa |grep flash flash-plugin-10.0.22.87-release.i386 [rkampen@media ~]$ sudo rpm -qa |grep fire firefox-3.0.6-1.el5.centos.i386
Try flash-plugin-9.0.124.0. I couldn't make flash-plugin-10.0.22.87 work on my 64-bit box.
# rpm -qa firefox flash-plugin flash-plugin-9.0.124.0-release.i386 firefox-3.0.6-1.el5.centos.x86_64
