They are not necessary per se, but running with all symbols loaded tends to
make the debugger run quite a bit slower.
The debugger normally defers symbol loading, and so when looking for a
symbol, first searches the already loaded symbols.
If you load all the symbols, then it has to scan the whole symbol space,
instead of just what has already been loaded.
The .reload /u unloads all the symbols, but the cached files stay in the
local symbol file cache.
The .reload /s puts the debugger back in to deferred loading mode, where it
loads what it needs and no more, since all the symbol files have been put in
the local cache, when a particular file is needed, loading it is very fast.
Furthermore searching for symbols is still fast, since many symbol file
loads are deferred, and the symbol space stays relatively small.
Joe.

Joe, just out of curiosity, why are the second two ‘.reload’ commands
necessary.
Thanks,

Read the docs about setting a cache at the start of your symbol path.
Then do a .reload /f - plan to wait for a long time. All the symbols will
get pulled down over the network to a local on disk cache.
Then do a .reload /u
Followed by a .reload /s
From then on, you shouldn’t be hitting the network much for symbols ever.
Joe.

Sounds like you might be hitting network timeouts. They are 30secs.
Do you have all your symbols cached locally?

About 5 minutes ago my target crashed, and *BUSY* has been shown ever since.
Now, having this happen frequently on the latest and greatest (cough cough)
WinDbg I know that about 40 minutes from now WinDbg will decide it isn’t
busy and I can finally do the !analyze -v I need to do to see why my driver
crashed.
I did do a Ctl+Alt+D with the following results. You can’t see it since no
timeline is in this dump but there were periodic pauses of ~ 20 to 30
seconds.
