Kernel panic - not syncing: kernel stack overflow

Hi, all,

 

When I boot the linux kernel, I had the following error. I totally lost, and don't know if there is anything I can modify to my configuration.

zImage starting: loaded at 0x00800000 (sp: 0x00b11eb0) Allocating 0x37bd64 bytes for kernel ... gunzipping (0x00000000 <- 0x0080c000:0x0099e149)...done 0x359fc4 bytes Attached initrd image at 0x0099f000-0x00b10bd0 initrd head: 0x1f8b0808 Linux/PowerPC load: console=ttyUL0 root=/dev/ram Finalizing device tree... flat tree at 0xb1e300 Using Xilinx Virtex machine description Linux version 2.6.30 (yixuan@localhost) (gcc version 4.2.2) #10 PREEMPT Sun Sep 20 03:30:43 BST 2009 Found initrd at 0xc099f000:0xc0b10bd0 Zone PFN ranges: DMA 0x00000000 -> 0x00030000 Normal 0x00030000 -> 0x00030000 Movable zone start PFN for each node early_node_map[1] active PFN ranges 0: 0x00000000 -> 0x00030000 MMU: Allocated 1088 bytes of context maps for 255 contexts Built 1 zonelists in Zone order, mobility grouping on.

Can anybody give some suggestion?

It seems like this is the same as "Kernel panic - not syncing: Fatal exception in interrupt" thread, is it?

 

If it is, did you get anywhere with the other recommendations?

Hi, John,

 

Sorry for the late reply, I was not in the office for the last week.

 

It was similar with the other thread. In the previous one, this error was only shown once, then never reproduced. 

I did all your suggestions, but with no luck. Any more suggestion please?

It makes it difficult to help when you start a new thread and I have to go back to the old thread for the informationa about what has been done in the past.

 

I'm going back to the old thread to continue.

Sorry. I thought that's two different errors. You can delete this one if you prefer.
