(fwd) Could be an upstream kernel issue lurking. ---------- Forwarded message ---------- Date: Fri, 20 Apr 2007 22:21:26 +0200 From: Mark Stier <markstier@...il.com> To: linux-kernel@...r.kernel.org Subject: FYI: Xen or kernel bug? Hello, tcp_vegas produces division by zero kernel oopses in dom0 when running a Xen-patched 2.6.16.28 kernel. I have tracked down the problem to line #256 in tcp_vegas.c: presumably due to flaky Xen timing, the rtt seems to get zero from time to time (adding 1 to the rtt variable solves the problem for me). The same should apply to line #140 in tcp_veno.c, too.
