Hi Joseph, Thank you for testing! I will submit this patch to the linux-watchdog community after adding commit log to patch. 2013/2/22 Joseph Salisbury <joseph.salisbury@xxxxxxxxxxxxx>: > The I/O data can be seen at: > https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1116835/+attachment/3540738/+files/iomem.txt In the case of SP5100 and SB7x0 chipset, the sp5100_tco driver overwrites a free resource I/O memory address obtained by allocate_resource() to the MMIO address registers for watchdog timer. In the case of M3A78-CM, the sp5100_tco driver was using 0xfed45000 as a MMIO address. Since 0xfed45000 is the free I/O memory resource address, this is the expected behavior. [ 18.852540] sp5100_tco: Using 0xfed45000 for watchdog MMIO address However, Rewriting the MMIO address registers for the watchdog timer must have generated the problem. I think that the problem has occurred with the chipset or the BIOS layer. So, It's difficult for me to investigate the problem, and the problem is critical. Thus, I decided to delete the concerned codes.
