Subject: [PATCH] powerpc/83xx: Fix PCI IO base address on MPC837xE-RDB boards
Date: Tue, 21 Jul 2009 01:36:43 +0400 [thread overview]
Message-ID: <20090720213643.GA4209@oksana.dev.rtsoft.ru> (raw)
U-Boot maps PCI IO at 0xe0300000, while current dts files specify
0xe2000000. This leads to the following oops with CONFIG_8139TOO_PIO=y.
8139too Fast Ethernet driver 0.9.28
Machine check in kernel mode.
Caused by (from SRR1=41000): Transfer error ack signal
Oops: Machine check, sig: 7 [#1]
MPC837x RDB
[...]
NIP [00000900] 0x900
LR [c0439df8] rtl8139_init_board+0x238/0x524
Call Trace:
[cf831d90] [c0439dcc] rtl8139_init_board+0x20c/0x524 (unreliable)
[cf831de0] [c043a15c] rtl8139_init_one+0x78/0x65c
[cf831e40] [c0235250] pci_call_probe+0x20/0x30
[...]
This patch fixes the issue by specifying the correct PCI IO base
address.
