[Qemu-devel] Weird bahaviour of TOP and cdrom under Qemu-system-ppc

[Tero Kaarlela]

Hi,

  I have been running debian 3.1r0a under Qemu-system-ppc(PREP). I just 
noted few coupleof things:

  1. Top gives really absurd values for processor % for few seconds then 
it crashes see http://personal.inet.fi/koti/ekasorvaus/qemuppc.png
  2. If I launch with -cdrom sarge.iso and start using this image under 
Qemu ie. mount gives a lot of hdb: DSC timeout


  That second one is really annoying and first one is posted because I 
thought it might tell about some bigger probs.

My host is debian X86 and qemu is CVS.

This is a known issue that have been discussed here before.
As a summary, I found that it can happen on real hardware in some
(undetermined) case.
I found bug reports about this point with Google.

Fabrice has a fix for this.
You can also edit hw/ide.c and comment the one-line Darwin hack (easy to
find).

   If this is what you mean:

#ifdef TARGET_PPC
         /* XXX: currently a workaround for Darwin/PPC. Need to check
            the IDE spec to see if it is correct */
-        ide_set_signature(s);
+        //ide_set_signature(s);


It seems to be removed from CVS.
