#74 Tulip driver freezes with kernel 2.4.26 and LNE100

[Anonymous]

Bug reported by Daniel Wagenaar,
wagenaar@alice.caltech.edu.

[Using format as per
http://www.kernel.org/pub/linux/docs/lkml/reporting-bugs.html.\]

1. Summary: Tulip driver freezes with kernel 2.4.26 and
Linksys Network Everywhere Fast Ethernet 10/100 model
NC100 (rev 17).

2. Details: Insmodding the tulip.o driver into 2.4.26
causes my (Athlon) computer to freeze. This doesn't
happen always instantly, but always within a second or
so. The computer is connected to a LAN. Previous
versions of the kernel (2.4.18) did not suffer from
this problem. I encountered this problem after
installing gentoo, but could reproduce it by compiling
2.4.26 under redhat. Intriguingly, the version of the
tulip driver at www.scyld.com/tulip.html, but not the
version in the 2.4.26 kernel tree, worked fine under a
previous version of gentoo, but caused a freeze under
latest version. Following data was obtained in a redhat
environment, with a kernel direct from www.kernel.org.

3. Keywords: network driver, tulip, module, 2.4.26.

4. Kernel version: 2.4.26

5. Oops: System freezes without oops.

6. Reproduce: "insmod tulip.o"

X. Other notes: In 2.4.18, all is well. In
/proc/ioports, the tulip driver is seen to grab the device:

d000-d0ff : tulip
d400-d4ff : Linksys Network Everywhere Fast Ethernet

and same in /proc/iomem:
