141 Say Y here if you want verbose debugging from the PM Suspend and

157 help
158 Enable the PM code's memory area checksum over sleep. This option
159 will generate CRCs of all blocks of memory, and store them before
160 going to sleep. The blocks are then checked on resume for any
161 errors.
162
163 Note, this can take several seconds depending on memory size
164 and CPU speed.

172 help
173 Set the chunksize in Kilobytes of the CRC for checking memory
174 corruption over suspend and resume. A smaller value will mean that
175 the CRC data block will take more memory, but wil identify any
176 faults with better precision.
