Hi,
I have a Sun Fire V215 that hangs with MP kernel but runs fine with
single processor GENERIC kernel. I did see userland memory corruption
with 7.8 GENERIC.MP, so I wanted to try recent IPI fixes. But with
snapshot it hangs buring boot. No break into ddb possible.
Rebooting with command: boot disk /bsd.snap -d
Boot device: /pci@1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1/disk@0,0 File and
