ls1046a(32bit) can't start without PAE mode

Question asked by lei maohui on Nov 12, 2018

Recently, I try to use kdump on ls1046a(32bit), but because of the CONFIG_PHYS_ADDR_T_64BIT has been enabled by CONFIG_PAE, kdump can't work normally.

So, I disabled CONFIG_PAE and try kdump again, but the 1st kernel can't start. It is blocked after output messages as following:

Is there any one give me some suggestions about how to disable PAE mode or how to use kdump on ls1046a?
