Bug#499231: updated initramfs-tools now kernel oops during boot sequence
 

Package: initramfs-tools
Version: 0.92k
Severity: critical
Justification: breaks the whole system

PowerPC (G4 Macintosh) running sid.
Ran nightly dist-upgrade which updated initramfs-tools.
Now the system crashes with a kernel oops.

I restored the old initrd.img...bak and it now boots OK.

curiously, after gunzip-ing and un-cpio-ing the two initrd.img files,
the only difference is:

greybox:/tmp# diff -r initrd initrd.BAD/
diff -r initrd/conf/initramfs.conf initrd.BAD/conf/initramfs.conf
7,8d6
< # In particular, Debian installer may set MODULES in the file
< # /etc/initramfs-tools/conf.d/driver-policy.
greybox:/tmp#

/var/log/syslog.0 attached (contains the kernel Oops and surrounding stuff)

not attached and aboves change cannot lead to unbootable state,
try to reproduce.

Ummmm. It was attached. It's definitely there on the CC I sent to
myself. But here it is again.


I know those changes can't cause an unbootable state. That's why I
said "curiously". It's definitely reproducable. If I put the bad
initrd.img back, it dies during the boot sequence repeatably. I have
another system running Sid. I haven't done a dist-upgrade on it
yet. So I'll see what happens there.


For what it's worth, I'm also attaching the dpkg.log file that show
what got updated in the fatal dist-upgrade.

Bug#499231: updated initramfs-tools now kernel oops during boot sequence
 

Here are two extracts of the syslog file one (failed) of a boot that
fails using the bad initrd.img, one (succed) of a boot that succeeds
using the good initrd.img.


I've stripped out the date/times and process-ids to make them diff-
able. The diff is interesting.

I did the dist-upgrade on my other G4 running Sid, and the oops
doesn't happen.


Looking at the syslog extracts, it seems that the failing machine
oops-es when it's trying to initialize its Radeon video driver. The
machine that doesn't oops has an ATI Rage video card. The traceback
also mentions radeon. So that's probably where the problem lies.


Do others with Radeon cards have this problem?

Here's the relevant part of "lspci -v" for each of the machines,
incase it's useful:
