Hello, I am trying to track down a (deadlock?) issue in CURRENT via DDB. The kernel does not complete hw probes on my Acer V5. I get stuck on apic_isr looping which leads nowhere. So I thought maybe things improve if I debug from another machine. What do you use for kernel debugging? According to the handbook kgdb over serial is a good option, do you agree? I'm on a netbook with no ethernet and no option for firewire: can I have a USB / nullmodem setup to work? I have no old-style uarts hardware anymore, as the handbook suggests... Any idea is welcome before I buy extra hw. I have a USB to serial showing up as /dev/cuaU0, do I need to grab another one and a nullmodem cable or there are better alternatives? Thank you.
