kexec problem on ls1046ardb

[zhengruoqin]

Hi All:

I have tryed to use kexec to boot the second kernel on ls1046a, but it failed.

Kernel Version: 4.16.67 from lsdk 1809

kexec-tools version: 2.0.16

Usage:

# kexec -l zImage
# kexec -e

Description:

I have tryed all the endian of system, include 32/64 big endian(32/64be) and 32/64 little endian(32/64le).

The result is that kexec can boot the second kernel, but the second kernel will panic during it's booting.

I think the panic is causd by the dpaa:ethernet driver, log is like:

[    2.778113] fsl_dpa soc:fsl,dpaa:ethernet@2: qman_init_fq(259) = -5

More detail is in the attachments. 

Could anyone help? 

Thanks.

Hello 若钦 郑,

After compiling off DPAA Ethernet in second image, the kexec/kdump should work fine.

This should be mentioned in the Release Notes.

DPAA should not be compiled in second kernel because of known hardware issue of DPAA1, that it does not support warm reset.

Have a great day,
TIC

By the way, I also find a strange problem, in arm32be, vmlinux can not be loaded properly, log is as follows:

NO response here, the second kernel can't be booted.
