Re: Bug#82873: ceil() severe bug on Cunzen
Hello all!
I havé no real clue here but I guess it is more a kernel thing than
anything else. At least my trusty old Jensen really needs a patch for
traps.c to be usefull. I believe the culzean to be the bigger brother of
the jensen. Therefore the bug in traps.c might affect this plattform as
well. For the J awk, gs, blender an a lot of other programs using for
example floor() simply went into a tight loog, eating all processor time
there was without ever coming back from a trap. The patch I used for
kernel 2.2.17 and 2.2.18 (well I just stole it from some other place I do
not remember anymore) can be found on www.alphalinux.org under
ftp://ftp.alphalinux.org/pub/Linux-Alpha/jensen/install/EV4-2.2.17.diff.
If dedian kernel sources include this patch already please ignore
my post, but pristine kernel sources from at least 16 upward need ths
patch on the old EV4 jensen.
Ahoi
