Hello,
I have a curious problem which at first sight seems related to the
end-June MFC of if_re :
- I 'mount -o nfsv3,intr,noconn,-r=32768,-w=32768
<-stable-server>:/files/bsd /files/bsd '
- (/usr/ports and /usr/src are symlinks to /files/bsd/*) quickly
after a portinstall/portversion etc. I get :
nfs server <-stable-server>: not responding
(and the corresponding process stuck in 'bo_wwa' according to
top(1) )
- though I still can 'ping <-stable-server>' and even 'ssh
me@<-stable-server-IP>'
- <-stable-server> works ok with two other -stable clients (using
if_bge) and all are compiled from the very same source-base (and
<-stable-server> works fine as well with a linux-client) which
seems to exclude nfsd-probs
- a kernel from June the 11th works ok
- downgrading if_re.c to revision 1.46.2.14 and if_rlreg.h to
revision 1.51.2.3 makes the problem disappear
- this is on my demo-notebook, I can test network stuff without much
limitations; I just use nfs on it for upgrading world and ports.
NB, same behaviour on amd64-stable and i386-stable (multi-boot same
hardware)
I can fill a PR if requested or feel free to contact me for further
testing.
Best regards,
Arno
PS: relevant pciconf info :
re0@pci0:8:0: class=0x020000 card=0x47011558 chip=0x816910ec rev=0x10 hdr=0x00
vendor = 'Realtek Semiconductor'
device = 'RTL8169 Gigabit Ethernet Adapter'
class = network
subclass = ethernet
otherwise standard kernel conf with stripped unneeded drivers and
extra :
device cpufreq
device atapicam
device sound
options TCP_DROP_SYNFIN (hint??)
