2009-04-17 08:59:23 Can't compile SVN kernel with CONFIG_DEBUG_SHIRQ

Hello,

When compiling the the SVN kernel with the CONFIG_DEBUG_SHIRQ set, the kernel crash when calling "request_irq" in the bfin_mac driver (bfin_mac_probe).

I think that's because the IRQ handler is called when it's registered but the "current_rx_ptr" global descriptor isn't initialized yet. Is it possible to call "desc_list_init" before requesting the IRQ?

Yes - However there maybe other problems then.

I don't see a reason why the Blackfin On-Chip MAC IRQ is requested with

the IRQF_SHARED flag set.

This doesn't make much sense to me.

I would simply remove the IRQF_SHARED flag.
