Okay, so we have two different problems here. One is "hang during suspend" with smp/highmem mode, and one is probably driver problem with p16v (whatever it is). /data/l/linux/sound/pci/emu10k1/irq.c: snd_printk(KERN_ERR "p16v: status: 0x%08x, mask=0x%08x, pvoice=%p, use=%d\n", status2, mask, pvoice, pvoice->use); ...aha, so you may want to unload emu10k1 for testing. Since you mention radeon in one of your other mails, just try it in vesafb mode...
