MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org On a few SMP boxes here, with kernels from about 2.4.14 though 2.4.17-pre2, the system locks up hard during heavy wireless I/O. Using in-kernel yenta_socket and orinoco drivers. Everything works 100% with a UP kernel, or an SMP kernel with max_cpus=1, but with 2 cpus, the system will lock up hard after just a few minutes of I/O. (Some have said the kernel pcmcia stuff is still immature, but Hinds' pcmcia-cs package doesn't work at all for me. It's ds.o keeps oopsing when insmod'ed, so I can't even try it.) With nmi_watchdog=2, I'm able to get an oops: ksymoops 2.4.3 on i686 2.4.16-pre1-smp. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.16-pre1-smp/ (default) -m /usr/src/linux/System.map (default) Oops: 0000 EIP: 0010:[] Not tainted Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010202 eax: 00012800 ebx: 4c15ff51 ecx: c03052d4 edx: ffffffff esi: 00100000 edi: 4c15ff51 ebp: c02dd060 esp: c179bf28 ds: 0018 es: 0018 ss: 0018 Process (pid: -2147450880, stackpage=c179b000) Stack: c02dd460 00000001 fffffffe 00100000 c011e7df c02dd460 c02d9800 c02d9810 c02d9810 c179bf74 00000046 c0108efd c0105290 c179a000 c0105290 00000000 00100000 c028df48 80008000 00000000 c023a990 c0105290 c179a000 c179a000 Call Trace: [] [] [] [] [] [] [] [] [] Code: 8b 3f f0 0f ba 6b 04 01 19 c0 85 c0 75 44 8b 43 08 85 c0 75 >>EIP; c011ea18 <===== Trace; c011e7de Trace; c0108efc Trace; c0105290 Trace; c0105290 Trace; c0105290 Trace; c0105290 Trace; c01052bc Trace; c0105322 Trace; c0119c28 Code; c011ea18 00000000 <_EIP>: Code; c011ea18 <===== 0: 8b 3f mov (%edi),%edi <===== Code; c011ea1a 2: f0 0f ba 6b 04 01 lock btsl $0x1,0x4(%ebx) Code; c011ea20 8: 19 c0 sbb %eax,%eax Code; c011ea22 a: 85 c0 test %eax,%eax Code; c011ea24 c: 75 44 jne 52 <_EIP+0x52> c011ea6a Code; c011ea26 e: 8b 43 08 mov 0x8(%ebx),%eax Code; c011ea28 11: 85 c0 test %eax,%eax Code; c011ea2a 13: 75 00 jne 15 <_EIP+0x15> c011ea2c Regards, Ian Morgan -- ------------------------------------------------------------------- Ian E.
