[Cbe-oss-dev] Problem with rebuilding latest Linux Kernel for PS3

[John Cunha]

Hi Geoff
 
As I said previously today, I've been trying to rebuild and use different kernels on the PS3 for a while now and never with any success.
The usual problems are that the kernel seems to build with success but the machine fails to reboot successfully using the newly build kernel.
 
I tried to build this kernel without the patch. 
Below are the exact steps I took and any notable screen warnings:
 
- Unpack the source file :        tar xjf linux-2.6.26.tar.bz2
- Descend into directory
- Create a local file called 'localversion' containing the text :       -20080726
- make mrproper- Copy config file:       cp arch/powerpc/configs/ps3_defconfig .config- Compile config:       make oldconfig
  (Note : During 'make oldconfig' I was prompted to answer some questions (all of which I just pressed 'return'):
      Forced module loading (MODULE_FORCE_LOAD) [N/y/?] (NEW)      /dev/kmem virtual device support (DEVKMEM) [Y/n/?] (NEW)      Hardware monitoring support (THERMAL_HWMON) [N/y/?] (NEW)      Framebuffer foreign endianness support (FB_FOREIGN_ENDIAN) [N/y/?] (NEW)      Cypress C67x00 HCD support (USB_C67X00_HCD) [N/m/?] (NEW)      ISP 1760 HCD support (USB_ISP1760_HCD) [N/m/?] (NEW)      USB Wireless Device Management support (USB_WDM) [N/m/?] (NEW)      iSight firmware loading support (USB_ISIGHTFW) [N/m/?] (NEW)      Accessibility support (ACCESSIBILITY) [N/y/?] (NEW)      Debug object operations (DEBUG_OBJECTS) [N/y/?] (NEW)
 
- Build the kernel:        make -j2- Make and install modules        make modules_install- Make the kernel         make install
   (Note: during 'make install' I got the following warnings:)       WARNING: No module uhci-hcd found for kernel 2.6.26-20080726, continuing anyway       WARNING: No module ps3disk found for kernel 2.6.26-20080726, continuing anyway       WARNING: No module ps3rom found for kernel 2.6.26-20080726, continuing anyway       WARNING: No module ps3disk found for kernel 2.6.26-20080726, continuing anyway
 
- Adapted the bootloader startup files by adding the new installed kernel. Executeed these commands:
    * echo "default=custom" > /tmp/yaboot.conf.new    * cat /boot/etc/yaboot.conf >> /tmp/yaboot.conf.new    * cat >> /tmp/yaboot.conf.new << EOF    * >    * > image=/vmlinux-2.6.26-20080726    * >         label=custom    * >         read-only    * >         initrd=/initrd-2.6.26-20080726.img    * >         append="video=ps3fb:mode:138 rhgb quiet root=/dev/ps3da3"    * >    * > EOF    * mv -f /tmp/yaboot.conf.new /boot/etc/yaboot.conf     * cp -f /boot/etc/yaboot.conf /boot/yaboot/yaboot.conf
 
- Finally reboot.
 
 
*** The problem ***
---------------------------
The machine starts ok and gets to the 'kboot:' prompt.I type 'custom' to load the new KernelLots of text comes up until the following line of text:   "ps3-ohci-driver sb_05: USB bus 1 deregistered"The screen then goes black and stays black and nothing else happens.
 
 
 
Note: The build steps I've taken from Remy Bohmer's site : http://www.bohmer.net/ps3_stuff/install-fedora-8-on-PS3.html
Can you tell me what I'm doing wrong?
Why have I never been able to build and use a kernel I have built?
Could the problem be related to the warnings of the missing modules during the 'make install'?
 
Many thanks in advance,
John
