D-Link DGE-550SX (dl2k): WARNING: at net/sched/sch_generic.c:219 dev_watchdog+0xda/0x12d()

Wed Nov 26 14:02:30 UTC 2008

Hello,
we just upgraded our old router (Fedora Core 5 on AlphaServer 800, kernel 2.6.17)
to new Fedora 10/2.6.27.5-117.fc10.i686 kernel on Core2Duo i686.

PCI-X Fiber 1000BASE-SX D-Link Network Adapter DGE-550SX, which worked fine in
old Alphaserver, freeze on new machine few minutes after start (What is interesting,
in one case after it sent exactly 8192 packets, an other cases are some multiples
of 8 too) and stop transmit packets. Only workaround (but for a while) is rmmod
+ modprobe its dl2k driver.

/var/log/messages contains following messages:

It is kernel bug, or some misconfiguration problem?
(DGE-550SX is 64bit bus PCI-X adapter, in our case pushed in standard
PCI 32 bit slot - but it should not be problem)

Thanks in advance, Franta Hanzlik
