PROBLEM:        (MCPM750D6 HPXQ36ADF)   (Patch ID: OSF375-370036)
********
A flaw exists in Digital UNIX SMP systems that results in duplicate
namecache entries being created.  Under heavy file system lookup operations
this can eventually result in a simple lock timeout and a system panic.

The typical crash data file stack trace will look like the following:

>  0 stop_secondary_cpu() ["../../../../src/kernel/arch/alpha/cpu.c"
   1 panic(s = 0xfffffc0000607a98 = "event_timeout: panic request") ["../../../../src/kernel/bsd/subr_prf.c"
   2 event_timeout() ["../../../../src/kernel/arch/alpha/cpu.c"
   3 xcpu_puts() ["../../../ ../src/kernel/bsd/subr_prf.c"
   4 printf() ["../../../../src/kernel/bsd/subr_prf .c"
   5 panic(s = "simple_lock: time limit exceeded") ["../../../../src/kernel/bsd/subr_prf.c"
   6 simple_lock_fault(slp = "simple_lock : time limit exceeded") ["../../../../src/kernel/kern/lock.c"
