Subject: Data translation registers/kernel stack

Hi,
reading translation registers from /proc/pal/cpu0/tr_info gives a page
size for the kernel stack (dtr 2) of 8k (2.4.25 kernel). Wondering and
looking through the whole linux kernel results in two things: First it
seems that PAL reports wrong page sizes since dtr 0 reports a 16k page
what is definitely wrong and second the kernel never ever inserts a 8k
page for the kernel stack instead uses the configurable granule size. My
machine is a ZX6000 900 MHZ Itanium2. May anybody having the same
machine and maybe a newer one (1.3 GHz, ...) confirm that bug? Is there
an update for PAL code?
My PAL version is
PAL_vendor : 0xff (min=0xff)
PAL_A : 6.6.23 (min=6.6.23)
PAL_B : 8.8.30 (min=7.6.0)
Christian
