Description David Craig 2005-10-04 05:20:09 UTC
Attempting to emerge sys-libs/readline-5.0-r2 results in system reboot.  The
system does reboot cleanly (executing the same scripts as 'init 6'), however, it
does so without providing any warning.

Reproducible: Always
Steps to Reproduce:
# emerge =sys-libs/readline-5.0-r2

or

# USE="" emerge sys-libs/readline


Actual Results:  
The during the compilation of the program a system reboot is triggered without
warning.  The output of emerge before the reboot is as follows:

Expected Results:  
I would expect the package to be merged without a reboot, or at least to give a
warning shortly before the reboot.

The only running service on this box is sshd, vixie-cron and syslog-ng.  I have
replicated the problem with these services switched off.  Other packages can be
merged without problems.

Comment 1 Markus Rothe (RETIRED) gentoo-dev 2005-10-04 05:42:25 UTC
seems to be related to bug #100023. I have had a realy small discussion about
this with tgall and ranger. we all three do not know wtf is going on. Our
toolchain/kernel seems to be broken somehow.

Can you please try compiling an older kernel (for example 2.6.9) and report back
if you can reproduce this problem using that kernel?

Another thing would be good to know: Which version of PowerMac do you have?
(something like "PowerMac7,2 with 2x2,5 Ghz" would be a good description)
Comment 2 SpanKY gentoo-dev 2005-10-04 06:17:09 UTC
not a bug in readline
Comment 3 Brent Baude (RETIRED) gentoo-dev 2005-10-04 06:44:36 UTC
Can anyone confirm if this *only* occurs off the install cd? or you getting in
chroots with stages too?
Comment 4 Brent Baude (RETIRED) gentoo-dev 2005-10-04 10:46:08 UTC
Ok I did some additional work on this.  I was on a known working g5 and I did a
chroot of stage1.  Stage1 was fine.  Then when I did the emerge -e system, it
did reboot on the configure of readline!  I was able to capture some of the
output which I will supply:

This bug can be demonstrated on a PowerMac7,3 2x2300.0 (PPC970FX).

It is definately not related to bug #100023 as I modified
"linux/drivers/macintosh/therm_pm72.c" to make the fan run at full speed (which
eliminates the problem experienced in bug #100023).  The bug (#108060) can still
be replicated even when both CPUs are relatively cool ( < 69C).

Unfortunately I cannot test this bug on kernel 2.6.9 as a bug in that version of
the kernel (in the i2c-keywest driver IIRC) causes a panic during boot. 
Comment 6 David Craig 2005-10-05 05:34:33 UTC
I managed to replicate this bug on kernel-2.6.9-r9.

I've been trying to recreate this on my power3 but to no avail.

into one of my spare testing partitions unpackage stage3, chroot, emerge -u
system, emerge sys-libs/readline  ...  nothing ....

curious!

Comment 10 Brent Baude (RETIRED) gentoo-dev 2005-10-18 12:44:12 UTC
I think it needs to be a 2005.1 chroot with current portage for it to fail Tom.

Also, I was able to circumvent the problem with:

 FEATURES="-sandbox -usersandbox" emerge sys-libs/readline

but I still dont know the cause of the problem. Help!

I just build stage1, stage2, stage3 with glibc-2.3.6-r3 and they built fine. seems like this was fixed upstream.

Please reopen if someone can reproduce this with a glibc version >2.3.5.
