Public bug reported:
The challenge here is that due to the limited functionality in the IBM Z and
LinuxONE console ("Operating System Messages" task)
a progress-bar is not replacing it's current line with an updated progress
(consuming just a single line), but just instead prints a new line on every
update.
Hence one line per update is printed and in case of high update intervalls that
swamps the console buffer and leads to partly unresponsive (browser-based)
console window (probably due to the high amount of data).
As an example we have here 145 lines, and with that updates, for the
"8%" download status - that makes up about 1500 lines in total for the
entire download (100%).

And since more lines got produced than the entire console buffer can store, it
results in the fact that the initial/first lines can not be reached while
scrolling up.
(In fact the 'oldest' msg one can get back to is roughly:
22250K .......... .......... .......... .......... 99% 79.2M 0s
)
A quick solution would be to reduce the update interval of that download
progress-bar - e.g. by 150:1 (if possible) .
In the early boot phase it lokks nicer - just a few lines are displayed:
"host : s1lp14"
"rootserver: 0.0.0.0 rootpath:"
"filename :"
"Connecting to 10.13.0.2:21 (10.13.0.2:21)"

The challenge here is that due to the limited functionality in the IBM Z and
LinuxONE console ("Operating System Messages" task)
a progress-bar is not replacing it's current line with an updated progress
(consuming just a single line), but just instead prints a new line on every
update.
Hence one line per update is printed and in case of high update intervalls
that swamps the console buffer and leads to partly unresponsive (browser-based)
console window (probably due to the high amount of data).
As an example we have here 145 lines, and with that updates, for the
"8%" download status - that makes up about 1500 lines in total for the
entire download (100%).

And since more lines got produced than the entire console buffer can store,
it results in the fact that the initial/first lines can not be reached while
scrolling up.
(In fact the 'oldest' msg one can get back to is roughly:
- 22250K .......... .......... .......... .......... .......... 99% 79.2M 0s
+ 22250K .......... .......... .......... .......... 99% 79.2M 0s
)
A quick solution would be to reduce the update interval of that download
progress-bar - e.g. by 150:1 (if possible) .
In the early boot phase it lokks nicer - just a few lines are displayed:
"host : s1lp14"
"rootserver: 0.0.0.0 rootpath:"
"filename :"
"Connecting to 10.13.0.2:21 (10.13.0.2:21)"
