Hey everyone, We made lots of progress on 2.6.32.3 patched up with
linux-2.6.32.3-ts7200_matt-5, using Martin Guy's recipe. THANKS AGAIN.
I can boot in single-user mode init=/bin/sh, but not with init=/sbin/init.
/dev/rtc* and /devttyAM* are all missing, though I can demonstrate most of the
goodies from linux-2.6.32.3-ts7200_matt-5.txt.
Our system: TS-7260 64MB, SD slot, with TS-SER2, and from what I can see,
there are posts here about 64MB Ram systems:
>>>>>>
Another is a problem that made 64MB ts7250's do the same thing due to its weird
memory bank placement: 8 8M banks at 0x0[0145]000000 and 0xe[0145]000000. The
vanilla kernel can't map such distant physical addresses and clags at the same
point as you are seeing. Maybe the '60 is the same.
Try adding mem= to your boot options. If that makes it boot,then either
you can just use part of the RAM with a string of mem=options or (better) apply
the discontigmem kernel patch to allow banks of memory at very distant physical
addresses.

Is this the issue we are having?

These kernel args do not resolve the issue on our system, and searching the
archives here reveal that I am not the first to stumble through this.
Apologies, but I'm a little lost about what to do next, and thought that
checking in you folks might be good. Should I:
A: Apply "discontigmen kernel patch"
or borrow some .config stuff from here
(http://tech.groups.yahoo.com/group/ts-7000/message/18141)::
B: CONFIG_DISCONTIGMEM_MANUAL=y
Really appreciated, I'm sorry our schedule is so tight!
