Subject: Re: new netfront and occasional receive path lockup
Date: Mon, 23 Aug 2010 16:26:52 +0200	[thread overview]
Message-ID: <1282573612.7881.2.camel@leto.intern.saout.de> (raw)

Hi yet again,

[not quoting everything again]

I finally managed to trigger the issue on the test VM, which is now
stuck in that state since last night and can be inspected.  Apparently
the tx ring on the netback side is full, since every packet sent is
immediately dropped (as seen from ifconfig output).  No interrupts
moving on the guest.

Still I'm wondering what would be the best course of action trying to
debug this now.  Should I have compiled some debugger into the
hypervisor? (gdbsx apparently needs that)

Thanks,
	Christophe
