Can you attach console output logs for each of configs above and also with NR_IRQS=128? That might give me some clues as to which specific code is causing the issues.
It really looks like the issue starts when irq_expand_nr_irqs is called the first time to make nr_irqs bigger than NR_IRQS. Andreas. -- Andreas Schwab, schwab@linux-m68k.org GPG Key fingerprint = 58CA 54C7 6D53 942B 1756 01D3 44D5 214B 8276 4ED5 "And now for something completely different."
