i'm guessing you're using ubuntu and thus dash is your /bin/sh ... shouldnt be 
a 2.6.24 issue

sadly, this is becoming a FAQ.  ubuntu ships a broken /bin/sh (dash) and thus 
some LTP scripts fall apart.  i would prefer to not change the scripts as the 
message is simple in LTP: fix your shell, dont add hacks to LTP.  otherwise 
we slowly back ourselves into this corner with the shell scripts where we try 
to support every craptastic shell out there and we're afraid to make any 
changes because we dont know what crappy shell is going to drop a brick.  LTP 
scripts are written to be POSIX complaint and only POSIX complaint shells 
should be provided by /bin/sh.
