# SLES15SP2

Dear all,



Unfortunatelly, I can°´t download °`LogFileArchive_2020-11-17T19_55_48+08_00.gzip°` file due to the following error.



---

HTTP Error 404.11 - Not Found

The request filtering module is configured to deny a request that contains a double escape sequence.

---



The SA system may have any problem.

BTW, I guess your system paniced when the SEL recorded °`Critical error°`. 

So could you please collect a crashdump by the following steps?



Steps:
1) Edit /etc/default/grub file

before:

GRUB_CMDLINE_XEN_DEFAULT="vga=gfx-1024x768x16 crashkernel=295M\<4G"

after:

GRUB_CMDLINE_XEN_DEFAULT="vga=gfx-1024x768x16 crashkernel=295M\<4G dom0=no-cpuid-faulting"

2) grub2-mkconfig -o /boot/grub2/grub.cfg
3) echo "kernel.unknown_nmi_panic=1" >> /etc/sysctl.conf
4) Edit /etc/sysconfig/kdump file



before:
KDUMP_DUMPFORMAT="compressed"


after:

KDUMP_DUMPFORMAT="ELF"

and

before:

KDUMP_COMMANDLINE_APPEND=""

after:

KDUMP_COMMANDLINE_APPEND="iommu=pt intel_iommu=on"



5) Reboot the system



6) Retest



7) When the problem reproduced, please check /var/crash/date/* files and give me the files.



Furthermore, could you please apply the latest kernel and xen packages? Please tell me the reproducibility.
