Problem: Booting into any kernel other than 2.6.5-1.358 will hang the system if Kudzu is enabled. Disabling Kudzu (or bypassing it in interactive startup) will allow bootup, but system is extremely sluggish and internet is unavailable. Steps taken so far: 1. I have installed via yum the '427, '435, and '435.2.3 kernels. Each time all indications were that the new kernels were successfully installed. I verified that grub.conf was updated properly. But each boot into these kernels produced the above problem, each time. 2. I have disabled IPv6 on this system by taking the following steps: 2.1 "install ipv6 /bin/true" is added to /etc/modprobe.conf 2.2 "NETWORKING_IPV6=no" is added to /etc/sysconfig/network 2.3 "alias net-pf-10 off" is added to /etc/modprobe.conf 2.4 "alias ipv6 off" is added to /etc/modprobe.conf "ifconfig -a" does not show an IPv6 address to my nic. 3. Compiled and installed 2.6.7 vanilla kernel. Verified grub.conf edited properly. Same results. 4. Thinking that the DNS cache might need to catch up, I booted into '435 and left the system on all night. No change in behavior. 5. I have been reading the fedora list closely, but I acknowledge I may have missed an important post under a general title. 6. I have promised not to top-post to any replies.
