Subject: sporadic kernel panic during boot (MPC8xx, FEC)
Date: Thu, 11 Apr 2002 09:07:44 +0200 [thread overview]
Message-ID: <3CB53640.9B0DD9B4@imc-berlin.de> (raw)
Hi there,
I am using the linux kernel from bitkeepers linuxppc_2_4_devel exported
as of -rv2.4.18 on a MPC855T based board.
>From time to time I see a kernel panic while booting. I suppose it
related to FEC (or MII) interrupts. The time the kernel panic occurs is
different every time.
Two examples:
