Comment (by pulkomandy):

 I found another way to reproduce this:
 * Install the php package
 * run php-cgi
 * interrupt it with ctrl+C
 * wait for a few seconds

 I increased NUM_LAST_CALLERS from 32 to 4096, and I do this:
 {{{
 kdebug> message
 PANIC: acquire_spinlock(): Failed to acquire spinlock 0xd3326dc0 for a
 long time!
 kdebug> spinlock 0xd3326dc0
 spinlock 0xd3326dc0:
   locked from 0x00000000
 }}}

 Should I try increasing it even more?
