There is a version of KDB that works reasonably well with the new
MCA/INIT model, in

ftp://oss.sgi.com/projects/kdb/download/v4.4/

  kdb-v4.4-2.6.14-rc1-common-1.bz2
  kdb-v4.4-2.6.14-rc1-i386-1.bz2
  kdb-v4.4-2.6.14-rc1-ia64-1.bz2

During MCA/INIT, the MCA/INIT handlers are the active tasks but you
almost always want to look at the task that was running when MCA/INIT
was delivered.  There is a new 'handlers' command on ia64, man
linux/Documentation/kdb/kdb.mm for details.

The register display (rd, r) and register modify (rm) commands still
need some work, in progress.  They always apply to the MCA/INIT
handlers, not the original task.  As a temporary workaround

  handlers hide (this is the default)
  set BTSP 1
  btc

Look for ia64_leave_kernel and copy the sp value immediately after that
line.  pt_regs <sp>+0x10 will give you the registers.
switch_stack <sp>-0x200 gives you the switch stack.
