Then, try to bring up the ethernet interfaces using the "ifconfig" command --> ifconfig crashes : toundra:~# lsmod Module Size Used by toundra:~# modinfo cassini filename: /lib/modules/2.6.17.11/kernel/drivers/net/cassini.ko author: Adrian Sun ([EMAIL PROTECTED]) description: Sun Cassini(+) ethernet driver license: GPL vermagic: 2.6.17.11 SMP preempt mod_unload gcc-4.1 depends: alias: pci:v0000108Ed0000ABBAsv*sd*bc*sc*i* alias: pci:v0000100Bd00000035sv*sd*bc*sc*i* parm: linkdown_timeout:min reset interval in sec. for PCS linkdown issue; disabled if not positive (int) parm: link_mode:default link mode (int) parm: cassini_debug:Cassini bitmapped debugging message enable value (int) toundra:~# toundra:~# modprobe cassini cassini.c:v1.4 (1 July 2004) eth0: Sun Cassini+ (64bit/66MHz PCI/Cu) Ethernet[0] 00:14:4f:24:47:a4 eth1: Sun Cassini+ (64bit/66MHz PCI/Cu) Ethernet[0] 00:14:4f:24:47:a5 eth2: Sun Cassini+ (64bit/66MHz PCI/Cu) Ethernet[0] 00:14:4f:24:47:a6 eth3: Sun Cassini+ (64bit/66MHz PCI/Cu) Ethernet[0] 00:14:4f:24:47:a7 toundra:~# ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: MII PHYAD: 1 Transceiver: internal Auto-negotiation: on Current message level: 0x000000ff (255) Link detected: yes toundra:~# ifconfig eth1 up Unable to handle kernel NULL pointer dereference tsk->{mm,active_mm}->context = 000000000000048e tsk->{mm,active_mm}->pgd = fffff80080736000 \|/ ____ \|/ "@'/ .. \`@" /_| \__/ |_\ \__U_/ ifconfig(1501): Oops [#1] TSTATE: 0000000080009605 TPC: 000000000041cf74 TNPC: 000000000041cf78 Y: 00000000 Not tainted TPC: <request_irq+0x14/0x500> g0: 00000000f0000018 g1: 000000000000ae78 g2: fffff800afe0d800 g3: fffff800aec56da0 g4: fffff800805d1260 g5: fffff8007fbf2000 g6: fffff800aec2c000 g7: fffff800ae5983a0 o0: 0000000000000000 o1: 0000000000000000 o2: 0000000000000001 o3: 0000000000000002 o4: 0000000000000010 o5: fffff800ae779d20 sp: fffff800aec2eda1 ret_pc: 0000000010002190 RPC: <cas_spare_recover+0x210/0x2a0 [cassini]> l0: 0000000000000000 l1: 0000000000000100 l2: fffff800aec504d8 l3: fffff800aec2f650 l4: fffff800aec56db0 l5: 00000000f7ea330c l6: fffff800aec504d0 l7: 00000000f8002000 i0: ffffffffffffffea i1: 0000000010003640 i2: 0000000004000000 i3: fffff800aec50000 i4: fffff800aec50000 i5: 104307a000000000 i6: fffff800aec2ee71 i7: 0000000010007cf4 I7: <cas_open+0x214/0x300 [cassini]> Caller[0000000010007cf4]: cas_open+0x214/0x300 [cassini] Caller[0000000000625ff0]: dev_open+0x50/0xc0 Caller[00000000006249c8]: dev_change_flags+0x128/0x180 Caller[0000000000675984]: devinet_ioctl+0x704/0x820 Caller[0000000000618ed8]: sock_ioctl+0x1b8/0x280 Caller[00000000004b18a4]: do_ioctl+0x24/0xa0 Caller[00000000004b198c]: vfs_ioctl+0x6c/0x360 Caller[00000000004b1ca8]: sys_ioctl+0x28/0x60 Caller[00000000004d2e94]: dev_ifsioc+0x54/0x320 Caller[00000000004ce0fc]: compat_sys_ioctl+0xdc/0x3a0 Caller[0000000000406c14]: linux_sparc_syscall32+0x34/0x40 Caller[0000000000011330]: 0x11330 Instruction DUMP: 02c64022 b0103fea a1322000 <c25c2008> 02c0401e b0103fed 27001c30 8214e140 80a40001 Killed toundra:~# ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
