Subject: Bug - regression - Via velocity interface coming up freezes kernel
Hi,
I observe problems with my machine freezing when bringing up the
network interface (via velocity based). Detailed report below.
First message was rejected because of html. Julia Lawall, sorry about
sending multiple copies.
[1.] One line summary of the problem:
Via_velocity interface coming up freezes kernel - WARNING: CPU: 0 PID:
1529 at /build/buildd/linux-3.11.0/kernel/softirq.c:159
local_bh_enable+0x60/0x90()
[2.] Full description of the problem/report:
Bringing up the network interface (using ifup) serviced by the
via_velocity driver the machine freezes once an ip address is assigned
via dhcp. No further interaction, neither via the just brought up
interface nor the serial console, is possible. A git bisect shows that
this behaviour was introduced with
2fdac010bdcf10a30711b6924612dfc40daf19b8.
During some of the freezes a kernel warning is printed to syslog. I
was unable to see this with 3.12.0-rc1. I was able to observe this
with v3.11-rc6 and different ubuntu kernels. The warning looks like:
WARNING: CPU: 0 PID: 1529 at
/build/buildd/linux-3.11.0/kernel/softirq.c:159
local_bh_enable+0x60/0x90(). Detailed message under point 10.
The second network interface on the board (using the via_rhine driver)
does not show this behaviour. The board in question is a via epia
sn18000g.

drivers/net/ethernet/via/via-velocity.c: update napi implementation
git bisect bad 2fdac010bdcf10a30711b6924612dfc40daf19b8
Because this bug is shadowed by another bug
(https://lkml.org/lkml/2013/8/3/40) I had to apply this patch
(http://lists.freedesktop.org/archives/dri-devel/2013-August/042668.html)
to the versions that would not compile to do the above bisect.
Output of last bisect step:
2fdac010bdcf10a30711b6924612dfc40daf19b8 is the first bad commit
commit 2fdac010bdcf10a30711b6924612dfc40daf19b8

drivers/net/ethernet/via/via-velocity.c: update napi implementation
Drivers supporting NAPI should use a NAPI-specific function for receiving
packets. Hence netif_rx is changed to netif_receive_skb.
Furthermore netif_napi_del should be used in the probe and remove function
to clean up the NAPI resource information.
Thanks to Francois Romieu, David Shwatrz and Rami Rosen for their help on
this patch.
