Problem for testing linux-next

Problem for testing linux-next

[Sidong Yang]

Hi, all.

I'm trying to test linux-next. I'm using QEMU for testing.
I cloned linux-next repository and checkout to last tag next-20210812.
I compiled with simple command below.

make menuconfig
make & make modules_install & make install

and rebooted system. and it failed.
It hangs after the message "freeing unused kernel image (init mem)
memory"
after about 500 seconds, it prints call trace including
"x2apic_send_IPI" and it blocked.
I want to copy and past it to here. but I don't know how to see the
dmesg in last failed session.

Is there any wrong configuration for compiling?
I would paste it if I could copy the error message.

Thanks,
Sidong

Make sure you have a working configuration based on a released kernel
version _first_ (like 5.13), before trying to test linux-next.  Once you
have that, then take that configuration and use it on the linux-next
tree so you know it is not a configuration issue.

good luck!

Yeah, I think it was configuration error. I reset all the configuration
and compiled 5.13 and it works. Also, I compiled with same configuration
linux-next and It was OK.

Thanks for tip!
