6.11.0-rc7 sh4eb "irq 123 nobody cared" panic?

Anybody else see this? I have it in the boot log of a test system from monday,
just got around to looking closer and the boot failed with...

printk: legacy console [netcon0] enabled
netconsole: network logging started
Freeing initrd memory: 560K
irq 123: nobody cared (try booting with the "irqpoll" option)
CPU: 0 UID: 0 PID: 19 Comm: scsi_eh_0 Not tainted 6.11.0-rc7 #1
