Hi Johannes & PA,

Johannes dragged up this old mail of mine as he has been having FB
related problems with CRX24 on his 735/125.

In my case, 32bpp FB on HCRX24 (Hyperbowl) on my B132L stopped working
at the time the FB reorganization patches went into the early 2.6
kernels. I have successfully been running 2.6.7-pa1 in 8bpp though.

Last night I compiled and booted 2.6.9-pa1. FB is totally hosed also
in 8bpp now. When the kernel switches to FB the screen gets "splattered"
with blue and red buffer debris and the machine hangs.

Looks like CRX/HCRX is suffering from chronic bitrot, possibly exarcebated
by the ia32/ia64-centric FB patches that have been going in lately.

So, is there anyone (Helge?) who has time and knowledge to look into
this? I can boot the B132L with the console on Vis-EG and torture the
HCRX24 on fb1 if that helps, but some clues would be good.

-Andy

Hi Andy,

I have two problems:
a) my time is sadly absolutely limited ATM,
b) I don't have any 24bit (HCRX or similiar) card - Maybe someone does not need his (e.g. as PCI (if it exists at all), or GSC, or EISA) ?

Anyway, I'll try to look into this at the weekend but right now I have no idea.

Helge

Hi Helge,

you are a wizard!!
After patching and compiling a 2.6.9-bk6-pa7-kernel it boots fine in 32bpp, 
did not try 8bpp yet, but could do so if useful.
The hppa "boot-penguin" looks a little bit psychedlic but everything, included 
X-server with "DefaultDepth 24", runs fine.
Will this patch make it into the kernel tree?

Many thanks for your work

Johannes
