 Hi
 
 and thanks for your work with this problem.
 
 As you expected crash silently just loops and I spotted the problem
 by turning on debug printouts.
 If I include printouts for the "cache" address, the first value seems
 reasonable, but then it starts to repeat with the value 0x00000001.
 Last, your patch solves the problem nicely. I get a warning about
 duplicate kmem_slab entry and crash continues to execute and issues
 other warnings indicating a corrupt vmcore file.

OK good -- I should have hq_xxx()'d that loop a long time ago.
Queued for crash-6.0.6.
Thanks,
  Dave
