My FC4 test 3 woes

[watermark]

When upgrading from fc3...

When booting into the gui install, after anacanda detects my ****z, all it will show is a white screen. The upgrade will run from text mode, however.

When it does upgrade via text mode, I get this info upon reboot:

root (hd0,0)
Filesystem type is reiserfs, partition type is 0x83
kernel /boot/vmlinuz-2.6.11-1.1286_FC4 ro root=/dev/hda1 rhgb quiet
[Linux-bzImage, setup=0x1600, size=0x18e793]
initrd /boot/initrd-2.6.11-1.1286_FC4.img
[Linux-initrd @ 0x1df0a000, 0xd6000 bytes]

Uncompressing Linux...Ok, booting the kernel
audit(1116432117.215:0): initialized
agpgart: Unsupported ALi chipset (device id: 1672)
RAMDISK: ran out of compressed data
invalid compressed format (err=1)
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown block(3, 1)

Any help? Or do I just have to wait for official to get rid of my woes?
(the agpgart thing was there in fc3 too, it shouldnt matter)

You could try rebuilding your initrd. Bring up the system in rescue mode from install CD1, your root partition should be mounted at /mnt/sysimage. Get you real system to "/" by entering command "chroot /mnt/sysimage". You may also have to mount /boot, "mount /dev/hdxxx /boot".

Save your old initrd : "mv /boot/initrd-2.6.11-1.1286_FC4.img /boot/initrd-2.6.11-1.1286_FC4.img.bak"

Create initrd, "mkinitrd /boot/initrd-2.6.11-1.1286_FC4.img 2.6.11-1.1286_FC4"

Return to rescue shell: "exit"

reboot: "exit"
