Hi Paul, Gavin,
Paul Romero wrote:
Some more information about the problem.
The next thing that executes is mount_block_root()--from
linux-2.4.x/init/do_mounts.c and it generates the
following message:
"VFS: Mounted root (romfs only) read only."
It then calls do_mount() for each FS that needs to be mounted.
I think ext2 systems are mounted first.
The rest of the diagnostic messages you commented
on originate as follows:
The "Bad boy: Colfire Timer (at 0x00022f50)
called request_irq without a dev_id!" is the only
one that really worries me. It is generated in
request_irq() in linux-2.4.x/arch/m68knommu/platform/5307/ints.c
when the request is made for a Coldfire timer
I assume exists on the 5307 version but not the
5249 version of the Coldfire CPU. Is this
a problem ?
That should be fixed, but it won't cause you any problems at
the moment. That interrupt routine doesn't use the dev_id
anyway.
Both the 5307 and 5249 use the same type of timer hardware.

Greg
The messages prefixed by kmem_create: come from the
kmem_create() routine in linux-2.4.x/mm and are just
diagnostics.
"Dentry cache hash table entries : 1024 (order: 1, 8192 bytes)"
comes from dcache_init() in linux-2.4.x/fs/dcache.c and looks
to be an informative diagnostic.
Inode cache hash table entries: 512 (order: 0, 4096 bytes)" comes
from inode_init() in linux-2.4.x/fs/inode.c and also appears diagnostic.
************ PREVIOUS MESSAGE ********
Quoth Paul Romero [paulr at rcom-software.com]:
The boot on my M5249C3 w/ 2 MB of Flash just began
hanging today. The last line it prints is as follows:
"NET4: Unix domaine sockets 1.0/SMP for Linux NET 4.0."
I certainly didn't change anything in my system setup and
think this may be indicative of a hardware problem.
The rest of the boot log follows and any ideas
would be appreciated.

There's an odd error right there...

All of those kmem_create errors seem odd to me too (I don't get them,
anyway, but then again, I use 2.6). Maybe something has changed in your
malloc or in your byte packing settings?

Maybe something is changing your serial port baud rate at this point, or
messing with the registers/pins that control your serial port (just a
wild guess)? What's the next line in a normal run? -- that might give
you some clues.
