Bug#646415: grub-ieee1275: system hang on G4 cube when running /usr/bin/os-prober (triggered during update-grub)

Package: grub-ieee1275
Version: 1.99-12
Severity: important
i found that update-grub was hanging this G4 cube while running
linux-image-3.0.0-2-powerpc and 3.0.0-2-powerpc-smp.
using sh -x, i was able to track it down to an invocation of os-prober:
0 togrul:~# sh -x /usr/bin/os-prober
+ set -e
+ . /usr/share/os-prober/common.sh
++ cleanup_tmpdir=false
++ cleanup_ro_partitions=
++ progname=
++ type mapdevfs
+ newns
+ '[' '' ']'
+ exec /usr/lib/os-prober/newns /usr/bin/os-prober
at which point the machine hangs -- mouse is unresponsive, video
terminal doesn't update, nothing over the network.
My current workaround is to add the following line to /etc/default/grub:
GRUB_DISABLE_OS_PROBER=true
But the system shouldn't just hang in regular operation like this.
i'd be happy to supply more debugging information or diagnostics.
Please let me know what you'd like to see.
Thanks for maintaining grub in debian!
Regards,
--dkg
