Subject: Potential problem in fec.c for 8xx
Date: Fri, 20 Sep 2002 14:49:21 +0200 [thread overview]
Message-ID: <3D8B1950.CE2DB9A1@corelatus.com> (raw)
When using MII, the interrupt for link status changes
is enabled before the PHY type has been detected.
If a link status change happens before PHY is detected,
you will get kernel panic in mii_link_interrupt
because the MII functions are undefined.
The correct way to do this would be to move the
enabling of MII interrupts from fec_enet_init
to mii_discover_phy3.
I can prepare a patch if someone points me to
the correct version to patch.
