Re: [9front] rpi4 shoots to 100% load and is unresponsive

Thanks , cinap.

I noticed that too, but I think my inexperience with hg screwed me, or maybe just too late when I was messing with it. I thought of trying to roll back to an earlier commit to see how things built, and I think I did 'hg update 7726', rather than the changset prior.

If I do 'hg update 7709', then 'mk' in /sys/src/9/bcm64, then copy the kernel over to /n/pidos, would that be heading in the right direction? Or should I revert the problematic commit in my working area, and see how that goes?
