Hi David,

dmesg is here:
https://gist.github.com/eddyz87/3a5f2a7ae9ba6803fc46f06223a501fc

Used the following commit from your branch:
ba1659e0f147 ("9p: [DEBUGGING] Don't release pages or folioq structs")

Still does not boot, unfortunately.
Are there any hacks possible to printout tracelog before complete boot somehow?

Thanks,
Eduard
