Description Kevin Fenzi 2009-01-24 22:30:21 EST
rawhide kernels including kernel-2.6.29-0.28.rc1.fc11.ppc and after don't seem to allow a normal boot on my ppc32 g4 machine.

The kernel loads and boots, but when it gets to: 

Setting up Logical Volume Management:

it locks completely. 
Adding in a strace I see it's stuck in a read of /dev/cdrom1
However, this machine only has a single cdrom, which on working kernels is just /dev/cdrom. 

Can anyone duplicate this?
Is there further info I can provide?

So... kernel-2.6.29-0.69.rc3.fc11.ppc boots just fine on my powerbook, which has a fully updated F10 + the aforementioned rawhide kernel on it. Could be some bad interaction between the rawhide kernel and rawhide lvm though, guess I should go raw-er on my powerbook...

Whoops, meant to add myself to the cc list... I've got a sacrificial G4 tower in the office I'll try to reproduce on, hopefully tomorrow...

Just rebooted into 2.6.29-0.99.rc4.git1.fc11.ppc and it worked. 

All I can figure is that it was some unspecified rawhide breakage that got fixed. ;( 

Should we try and track it down more? or just be thankfull and move on?
Either is fine with me.

Turns out there was a ppc32-smp-specific bug biting me, in addition to some apparent video hardware related issues tripping up plymouth... But I finally have a rawhide kernel booting on my dual 800 G4 tower, after adding a patch jwb pointed me at:


Going to tack that onto rawhide in a sec, but I suspect it'll get into linus' tree RSN.
Comment 5 Jarod Wilson 2009-02-12 17:03:00 EST
Never mind, its already in linus' tree, we'll just pick it up from the next git snap rebase.
Comment 6 Jarod Wilson 2009-02-12 17:12:13 EST
So yeah, lets just chalk this up to development kernel churn and close it for now...
