Description Marcin Kurek 2008-01-29 20:49:54 UTC 
Today I give a try to 2.6.24 on my machine (Pegasos 2 G4, 1GB) and it seems that
libata is broken for pegasos in this version again. Previous bug report was
https://bugzilla.redhat.com/show_bug.cgi?id=247602 and it was solved using
https://bugzilla.redhat.com/attachment.cgi?id=167747

This fix seems to be included in 2.6.24 (As
556ecf9be66f4d493e19bc71a7ce84366d512b71) but booting using 2.6.24-7.fc9 fails
on pata_via. Quick look at dmesg shows both channels are setup to use IRQ 14 and
this is not correct.

....
ata1: PATA max UDMA/100 cmd 0x1000 ctl 0x100c bmdma 0x1020 irq 14^
ata2: PATA max UDMA/100 cmd 0x1010 ctl 0x101c bmdma 0x1028 irq 14^

Acording to http://patchwork.ozlabs.org/linuxppc/patch?order=date&id=16281 this
problem should be fixed by
http://patchwork.ozlabs.org/linuxppc/patchcontent?id=16281

I wonder can anyone build a .24 kernel with this patch to verify ?
Comment 3 Marcin Kurek 2008-02-02 19:00:46 UTC 
I build a custom 2.6.24 today with this patch
(http://patchwork.ozlabs.org/linuxppc/patchcontent?id=16281) and I must say it
fix libata problems.
Comment 4 Marcin Kurek 2008-02-09 18:27:33 UTC 
Ping ? Any chances to see this fix in to rawhide 2.6.24 ?
Comment 5 Chuck Ebbert 2008-02-11 00:36:58 UTC 
Sorry, patch fell through the cracks. Will take another day before the kernel
build picks this up since today's build is already running.
