The same kernel, same machine, but compiled with CONFIG_MK7 runs
just lsof just fine.
To follow up on this, it appears that things are getting stuck while
reading /proc/*/maps, specifically it hangs in fs/proc/task_mmu.c in
m_start() at down_read(&mm->mmap_sem). The same thing happens when
trying to readlink /proc/*/exe.
I'm really not sure why this lock is getting stuck. Can anyone
reproduce this?
