I was able to narrow down a couple problems.
- scsi problems
also exists with a UP kernel, seems to be CONFIG_SCSI=m and
CONFIG_SCSI_MULTI_LUN=y that causes it.
- init hangs from serial console
I had a bug in synchronize_irq, drop this version in instead:
void synchronize_irq(unsigned int irq)
{
unsigned int cpu_irq;
cpu_irq = irq & (NR_IRQS - 1);
while (sparc_irq[cpu_irq].flags & IRQ_INPROGRESS)
cpu_relax();
}
- only cpu #0 handles interrupts
Need to implement smp4m_irq_rotate().
Bob
