[Xen-devel] Re: DomU panic in net_rx_action *initiated by another DomU*; 7503:20d1a79ebe31

I think this issue is at least approximately understood, and is present
in all xen x86_64 kernels:

rogue read-only mappings to linux heap pages left over from the 'initial
mapping' are preventing the netfront driver unmapping pages to hand over
as rx free buffers. This is compounded by the failure handling path
being slightly borked.

I'm sorry to be a bother -- but is there any ETA on a fix, or a bugzilla entry by which I can track this issue? The only netfront-related checkin I see to bugzilla is a fix for bug#183, and that appears to be distinct (I'm not getting the "#### netfront can't alloc rx grant refs", and so would appear not to be hitting that code).

This is happening quite frequently for me, even when I'm *not* using the kernel with the unstable module which triggers it every time.

If there is no bugzilla entry, I'd be glad to start one -- but since the issue is described as already understood, it sounds like there's likely already a bug for it that I'm just not seeing.
