Description Martin Kolman 2016-05-19 16:32:37 UTC 
Description of problem:
The kdump addon TUI checks user suggested reserved memory size but does not display it anywhere. This complicates inputting a valid value quite a bit, especially as the range changes due to RAM size and other factors.

Version-Release number of selected component (if applicable):
Kdump in RHEL 7.2

How reproducible:
always

Steps to Reproduce:
1. start installation in text mode
2. enter the kdump spoke
3. try to set the amount of reserved memory

Actual results:
The option simply says "Reserve amount(MB)" without any indication which values are accepted. The basically has to guess which value fits to the expected range as incorrect input only returns the unhelpful "You have provided an invalid value" error message.

Expected results:
The option shows the range of valid reserved memory values, for example:

"Reserve amount (128-1792 MB)"

This makes it easy for the user to set the correct value.

Additional info:
I have opened a pull request that makes the kdump addon TUI display the valid reserved memory range:
