[c-nsp] 2821 spurious reload

[Pete Barnwell]

I've had a 2821 reload unexpectedly -sh ver shows a bus error as below

#sh region address  0x4224F26C
Address 0x4224F26C is located physically in :

  Name  : text

  Media : R/O
  Start : 0x4000F000
  End   : 0x43F7FFFF
  Size  : 0x03F71000

This suggests to me hardware rather than software from Googling?

The routers got its original 256Mb  and an additional 512Mb stick in it
- is it possible to tell if this is a memory error from this, and if so
which stick might be the problem?

I have no Smartnet on this, so can't ask TAC :(

Thanks
