Subject: Re: [x86/vsyscall] 3dc33bd30f Kernel panic - not syncing: Attempted
 to kill init! exitcode=0x0000000b

Sorry for missing one info. Read the log and find the paniced host is
running with 'fips=1', And tried without this parameter, same kernel,
result are fine. so this looks like related to fips crypo or addr
random.
