Would one of you mind opening an LU on this?

But you probably wants to keep 7.7 kernel ? :)


If possible, yes. :)

Hi,

I've successfully compiled Lustre after the

'LU-12457 kernel: RHEL 7.7 server support' change

but when I try to create an MGS with LDISKFS backend

on RHEL 7.7 I get CPU soft lockup:

 kernel:NMI watchdog: BUG: soft lockup - CPU#1 stuck for 23s! 
[mkfs.lustre:31220]



Looked into logs for more details:
