Some more updates:
This machines run the upcoming 7.1-ppc with autofs-4.0.0pre9.
When I install 7.0-ppc it runs rocksolid with the same kernel binary.
7.0 came with autofs-4.0.0pre7:
Linux plum 2.4.1 #1 Sun Feb 11 11:56:01 GMT 2001 ppc unknown
Kernel modules 2.4.1
Gnu C 2.95.3
Binutils 2.9.5.0.24
Linux C Library x 1 root root 4209204 Oct 4 21:42
/lib/libc.so.6
Dynamic linker ldd (GNU libc) 2.1.3
Procps 2.0.6
Mount 2.10m
Net-tools 1.56
Kbd 0.99
Sh-utils 2.0
Modules Loaded snd-card-awacs snd-pcm snd-timer snd-mixer snd
soundcore ipv6 netlink_dev nfsd autofs bmac pcmcia_core
(hmm, it loads autofs and not autofs4 on 7.0?)
It hangs again after a while, in this case:
cc1plus 19126 181495 2903920 4 u01783c18 c44ca000 1 current
automoun 19129 183289 2932624 54 u0176a368 c42ca000 0 current
_spin_lock(c021b754) CPU#1 NIP c0 072f18 holder: cpu 0 pc C0057A18
I will try the older autofs package now.
