Kernel 2.8.6.1 & VLAN & E100

Hi everyone,

I am currently using Fedora Core 2 on a P3 w/512MB
RAM, 2 x 18.2GB SCSI in RAID1 via an IBM ServeRAID-4M.
Network card is an Intel 100 S controller.

All except the kernel is stock FC2. The kernel is
2.6.8.1 and compiled from the tarball found on
ftp.kernel.org .

Everything works fine until I tried to enable VLAN and
use VLAN subinterfaces. The VLAN subinterface comes up
fine but the moment I send traffic in/out of the
interface (i.e. ping), a huge and neverending chunk of
"bad scheduling while atomic" errors pop up
immediately and does not go away until I press
CTRL+ALT+DEL.

An extract of the error can be found below. But when I
run the system in normal non-VLAN mode, the problem
does not occur. So I am inclined to believe it either
has something to do with the VLAN driver or VLAN
driver + INTEL 10/100 driver.

Has anyone encountered before or know of any
solutions?

Please reply to me off-list as I am not subscribed to
the mailing list.

TIA!
