Bug#490694: Invalid ROM signature??
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi,
I was able to get my hands on another powermac, approximately the same
vintage, to experiment with and discovered that a (locally built) 2.6.25
kernel will boot on it (which is doesn't on my machine, with the oops
assoc with this bug). However it does have in its dmesg at the (bug)
corresponding point, the following,:
aty128fb: Invalid ROM signature 1111 should be 0xaa55
aty128fb: BIOS not located, guessing timings.
Sooooo, although it is a different machine, possibly are some memory
conflicts/bad_data associated with the aty128fb driver causing the oops?
Additionally, the PCI device being probed at that point is the agp card,
e.g.
0001:11:04.0 VGA compatible controller: ATI Technologies Inc Rage 128 RE/SG
A locally built 2.6.24.7 kernel works just fine.
