<damo22>i know spl was tiered but since we removed that why not clean up spl.S as well?

<damo22>youpi: i think i fixed interrupts and now i have a new deadlock in gnumach

<youpi>deadlocks are usually not about just one cpu

<youpi>and you need to look at all cpu states

<damo22>i did, the rest are idle or halted

<damo22>this thread is stuck

<damo22>i will mail in my irq fix

<damo22>it fixes the usb stack from affecting the rumpnet irq

<youpi>stuck: it's looping forever in that for loop?

<damo22>let me reproduce and check

<damo22>it hasnt happened again yet
