Slow boot on rocky linux 10 latest kernel
-
Hello,
When i boot a Rocky Linux 10 with the latest kernel, it's very slow on cpu XXX spinlock event irq.
Someone have the same issue ?
Thanks !

I'm not familiar with the Rocky 10 kernel internals, but a
spinlockstorm on a vCPU during boot often comes from how the guest kernel handles its paravirtual clock/timer with the host, rather than anything Rocky-specific.
Could you share your XCP-ng version, and whether an older RL10 kernel (or an RL9 one) boots normally on the same VM? That would tell us if it's genuinely the latest kernel that regressed.
If it only happens on that kernel and it's hard to test elsewhere, a mention to @Team-Hypervisor-Kernel might help, since they can check whether it reproduces on their side. -
@poddingue FWIW I've seen the same on FC44 as well, but I don't yet know where it came from.
