Slackware-current: kernel panic with 5.4.1 on x86
by Chalapticus from LinuxQuestions.org on (#4VYVY)
Hi Forum,
I have two older x86 machines (Acer Aspire One & Asus EEEPC 1201HA) with Intel Atom CPUs. On both of them the new 5.4.1_smp kernel will panic/oops during early boot.
The 4.19.* kernels ran just fine along all kernel upgrades.
Also, I have *no* such problem with the 5.4.1_smp kernel on x86_64.
In order to investigate I ran the new (from 2019-November-30) x86 `usbboot.img' with `qemu-system-i386'. When I did *not* specify the CPU (using default) the image booted. However, when setting the cpu to n270 (similar/same to what I have) I got `oops 9', just like on my real HW.
Running the following command
Code:qemu-system-i386 -enable-kvm -cpu n270 -m 1G -hda usbboot.img -serial stdio | tee failed-x86-boot.logand setting `console=ttyS0' to the kernel I captured the output of the boot.
Please find the log attached.
For me the line `BUG: unable to handle page fault for address: f7d97005' seems
peculiar, but I have no clue about kernel development.
Any insight would be appreciated.
Thank you in advance.
