[linux-pm] write_page hang in close_swap

[luming.yu at intel.com (Yu, Luming)]

Hi Pavel,

I found a problem in function close_swap (kernel/power/swsusp.c). 
the first call to write_page just hang on my IA64 platform.:

  error = write_page((unsigned long)&swsusp_info, &entry);

But the preceding calls to this function in data_write() and
write_pagedir() 
are 100% done without any visible error.

Have you ever encountered this before on other platform?

Thanks,
Luming
