Summary: de4x5 does not work with SMP Kernel Version: 2.6.1 Status: NEW Severity: high Owner: jgarzik@pobox.com Submitter: thomasz@hostmaster.org
I am successfully using a "Digital Equipment Corporation DECchip 21041[Tulip Pass 3] (rev 11)" with the de4x5 driver under linux 2.4.*. Linux 2.6.1 works fine when compiled for UP but when compiled for SMP it does lockup within milliseconds after bringing up the network interface. After enabling the NMI watchdog I received the following oops message (copied manually, case not preserved, typos possible):
NMI watchdog detected lockup on cpu0, eip e29a1528, registers: cpu0: 0 eip: 0060:[<e29a1528>] not tainted eflags: 00000086 eip is at .text.lock.de4x5+0x30/0x78 [de4x5] eax: 00000040 ebx: 00000282 ecx: c03ef194 edx: 00000000 esi: df5a1200 edi: df5a1000 ebp: 0000c400 esp: c047bee0 ds: 007b es: 007b ss: 0068 process swapper (pid: 0, threadinfo=c047a000 task=c03ec980) Stack: df5a1000 df5a1200 00000001 df5a1000 000000fa e299a873 df5a1000 00001010 00001010 0000ef01 0000ff3f 00000008 00000960 df5a1200 df5a1000 000000fa c047bf50 e299955c df5a1000 00000007 e29994d0 df5a16f8 c150b520 c0127717 call trace: e299a873 dc21041_autoconf+0x223/0x630 de4x5 e299955c de4x5_ast+0x8c/0xb0 de4x5 e29994d0 de4x5_ast+0x0/0xb0 de4x5 c0127717 run_timer_softirq+0xd7/0x190 c0122fc7 do_softirq+0xc7/0xd0 c0115bfd smp_apic_timer_interrupt+0xcd/0x140 c0105000 rest_init+0x0/0x50 c0109a0e apic_timer_interrupt+0x1a/0x20 c0106cb0 default_idle+0x0/0x40 c0105000 rest_init+0x0/0x50 c0106cdc default_idle+0x2c/0x40 c0106d6b cpu_idle+0x3b/0x50 c047c8ed start_kernel+0x15d/0x170 c047c4a0 unknown_bootoption+0x0/0x120 code: f3 90 80 be 0c 02 00 00 00 7e f5 e9 6a b3 ff ff f3 90 80 bb
Using the de2104x driver is not an option as it fails to receive or transmit any packets according to tcpdump and even in UP mode.
