You have it slightly wrong...
print $hashref{'disks'}->{'io'};
...And the quotes are optional (usually)...
print $hashref{disks}->{io};

Thare are other lists/newsgroups, but most are geared to specific port
(ActiveState), or modules (Tk). This is a good list for any beginner(ish)
question, no matter the subject... just as long as it is a Perl question.

Subject: accessing a hash map...
This may not be the right thread but I'd like to see if someone could point
me to the right direction. I'm writing a CGI script to show current
performance of the Apache server and I'm using Linux::stat to get the disk
IO for example. I can seem to access the value of the hash reference(see
below). Does anybody have any thoughts? Is there a more generic mailing
list for the different perl modules? I know there's the mod_perl thread but
its more for Apache. Any help will be greatly appreciated. Thanks!
use Data::VarPrint;
use Linux::stat;
my $stat = Linux::stat->new( [ stat => "path to /proc/stat" ] );
my $hashref = $stat->stat();
print $hashref{'disks'}=>{'io'};
