Re: Kernel oops, sig: 7 at last init / modules

Dear Etienne,

in message [ref] you wrote:

We are using an MPC8260 on a custom board with 16MB RAM,
16MB FLASH, DS1558W RTC, LAN83C183 PHY etc. I use Denx's
U-Boot 0.4.0 for the boot loader, and then their PPC82xx
embedded linux from their ELDK.

You should use a more recent version of both the U-Boot  sources  and
especially the Linux kernel.

For me it seems that the problem comes from executing a
module on the file system (either on NFS or Ramdisk).

Normally no modules are used at all.

Check this!

Call backtrace:
C00401C8 C0033434 C0003B7C 00000000 0FF1A05C 0FF4FBF8
0FF4EA04
0FF4F858 0FF4C4C8 0FF85B60 0FF85998 10015108 0FEE67B8
0FECFF74

Decode the backtrace (see ftp://ftp.denx.de/pub/tools/backtrace)

Furthermore, if I cross-compile my own simple program (that
opens devices etc) I am able to run it flawlessly for a
long time by passing an init=/tmp/myprogram argument to the
kernel - no oops generated there...?

To me it seems that you should check your memory  map.  For  example,
where  is  the  IMMR  mapped? Did you make sure to put it at a "high"
address?


Best regards,

Wolfgang Denk
