David,

Thanks for the response. I searched a little more and found that many people
recommend looking through __log_buf to see if info is getting printed to
memory. Below I've added the printouts I get both before and after the
system hangs. Also, I'm not using Uartlite. I'm using 16550; however, I have
created the same design with Uartlite and adjusted the console parameter to
reflect that change. In both instances the kernel hangs. You're right too,
this is common...I just need to figure out how to read out this __log_buf
address:

If I stop the processor after it hangs:

... This looks like ASCII text; let's try decoding it...

XMD% mrd 0xc0259fa4 10
C0259FA4:   3C353E5B    '<5>['
C0259FA8:   20202020    '    '
C0259FAC:   302E3030    '0.00'
C0259FB0:   30303030    '0000'
C0259FB4:   5D204C69    '] Li'
C0259FB8:   6E757820    'nux '
C0259FBC:   76657273    'vers'
C0259FC0:   696F6E20    'ion '
C0259FC4:   322E362E    '2.6.'
C0259FC8:   32352D72    '25-r'

Looks like you've found how to read the logbuf; now you just need to
dump it to a file so tha tyou can read it.  :-)
