SH kernel boot up issue

SH kernel boot up issue

[Tung Pham]

Hi,

I have an old working kernel for my SH board and now I'm trying to move
it to a newer version. The approach is to merge some patches of old
kernel to new one.

Currently I have an issue with boot up new board. The board can be boot
up successfully but after awhile the board reboot automatically. There's
nothing inside the dmesg and syslog. I tried to add printk in some
suspend/shutdown function but nothing logged out.

Do you have any idea to fix this issue?

Thanks,
-Tung

Hi Mike,

I'm working on custom board that uses sh-7710 cpu, and I tried to boot
with kernel version 2.6.35.13.

Do you have any idea for this?
BTW: last kernel worked : 2.6.15

Thanks,

can you try 2.6.30 and 2.6.31 ?  your crash sounds like a PCI/DMA error i 
reported w/7750 that shows up starting with 2.6.31.

Mike,

Do you have the bug ID for your issue?

Thanks,

Think environment!

Could this be affecting 7751 as well? I have a board which reboots 
in a couple seconds after the kernel is loaded in. 2.6.22 booted fine on 
that one, but with a recent kernel it's just looping in reboots.

Thanks,

Never mind, I found that thread :)

Hi,

Issue still happens on v2.6.30. I wonder why CPU reboot without
information (CPU reboot every 5 minutes).

Thanks,
