Hi,
this PowerBook G4 was running 3.16 for a while but now I wanted to upgrade
to latest mainline. However, during bootup the following happens:
===============================
[ 2.237102] ata1: PATA max UDMA/100 irq 39
[ 2.401708] ata1.00: ATA-8: SAMSUNG HM061GC, LR100-10, max UDMA/100
[ 2.401764] ata1.00: 117231408 sectors, multi 16: LBA48
[ 2.417633] ata1.00: configured for UDMA/100
[ 44.918102] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0
[ 44.920452] ata1.00: failed command: READ DMA
[ 44.922725] ata1.00: cmd c8/00:88:64:c2:12/00:00:00:00:00/e0 tag 0 dma 69632 in
[ 44.927257] ata1.00: status: { DRDY }
[ 49.971784] ata1.00: qc timeout (cmd 0xec)
[ 49.976529] ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4)
[ 49.978908] ata1.00: revalidation failed (errno=-5)
[ 55.019662] ata1: link is slow to respond, please be patient (ready=0)
[ 60.007677] ata1: device not ready (errno=-16), forcing hardreset
[ 60.012670] ata1: soft resetting link
[ 60.193638] ata1.00: configured for UDMA/100
[ 60.196158] ata1.00: device reported invalid CHS sector 0
[ 60.198610] ata1: EH complete
===============================
This happens only once, but systemd thinks there's a hard problem and will
drop to a recovery shell. I can start sshd and login remotely and then the
system appears to be running just fine.
This happened in 4.2.0-rc5 so I went back a few versions and found that
4.1-rc5 was OK (the error does not show up and the system boots just fine)
and 4.1-rc6 is not.
Unfortunately a git-bisect between these two versions went completly off
the charts, I don't know what happened here:
==================================
first bad commit:
0fa372b6c95013af1334b3d5c9b5f03a70ecedab is the first bad commit
commit 0fa372b6c95013af1334b3d5c9b5f03a70ecedab
Author: Takashi Iwai <[email protected]>
Date: Wed May 27 16:17:19 2015 +0200
ALSA: hda - Fix noise on AMD radeon 290x controller
==================================
I don't have this driver (or ALSA) even selected. I can reproduce this
error pretty reliably and I'd like to attempt another git-bisect
run when I'm more awake. But maybe somebody recognizes this error and
has a hint where this could come from?
dmesg & .config: http://nerdbynature.de/bits/v4.1-rc6/
Thanks,
Christian.

Interesting, I'll try to reproduce it on my G4.

Can you send me your .config or did you use my .config, verbatim?
I'll try another git-bisect later today.
Thanks,

Yes that would explain why the bisect went wrong. If you have an intermittent
bug like that you have to be very careful about which commits you mark good or
bad.
I don't really know anything about disk drivers, so hopefully someone who does
can chime in.
cheers
