This happens with sym2. The same kernels boot on A500-44 but hang on A500-65 (650Mhz). It smells like a deadlock. I don't believe this is a result of interrupt distribution. I can't say for sure since I've had the IRQ distr code in my tree for a while. I don't think I've ever booted rp2470 with 2.4.19. I will try sym1 driver *and* try disabling IRQ distribution in the next couple of days. I've reproduced the hang twice with 2.4.19-pa18. Console output stops after first line of either "sym3:" output or "sym4:" (ie only one line is printed for that interface. TOC had the following: CPU0 0x10143420 timer_bh+200 CPU0 0x102276fc sym53c8xx_timer+ec CPU1 0x1010dd40 do_irq+100 CPU1 0x102275f0 sym53c8xx_intr+140 and CPU0 GR02 0x10143420 timer_bh+200 CPU0 IOAQ 0x102276fc sym53c8xx_timer+ec CPU1 GR02 0x102274f4 sym53c8xx_intr+44 CPU1 IOAQ 0x102275f0 sym53c8xx_intr+140 I hoped someone else has a chance to look at this too. The rp2470 (gsyprf11) is externally accessible if a volunteer has time to dig into this. Or let me know what I might try next. thanks, grant
