sparc10 with 512M of RAM hangs on boot

sparc10 with 512M of RAM hangs on boot

[Ron Calderon]

every kernel after 2.4.0-test5 hangs my sparc10
at the same spot. Has anyone looked into this?
here is screen output:

SPARCstation 10  (1 X 390Z50), No Keyboard
ROM Rev. 2.12, 512 MB memory installed, Serial
#6299671.
Ethernet address 

Boot device: /iommu/sbus/espdma/esp/sd@3,0:c   File
and args:         
SILO boot: 
Uncompressing image...
PROMLIB: obio_ranges 5
bootmem_init: Scan sp_banks, 
init_bootmem(spfn[121],bpfn[121],mlpfn[c000])
free_bootmem: base[0] size[c000000]
reserve_bootmem: base[0] size[121000]
reserve_bootmem: base[121000] size[1800]

the last kernel I tried was cvs'ed from vger last
night. I beleive it was 2.4.1-pre2.

Well, that's when highmen support was introduced into sparc32, right?

That's quite the same output I get. However, supplying mem=128M
(I have got 128MB) at least allows me to boot up with about
25MB of RAM (sparc has holes...):

It's a SparcStation 10 w/ 2 CPUs.

Anton, do you have any clue where changes could have broke SS10 support?

Yep I know about this but need to iron out another bug with the patches
before I commit them.
