http://bugzilla.kernel.org/show_bug.cgi?id=11426 Summary: reproducable panic when reading cdrom (atapi dma) Product: IO/Storage Version: 2.5 KernelVersion: 2.6.26.3 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: IDE AssignedTo: io_ide@xxxxxxxxxxxxxxxxxxxx ReportedBy: mathis.ahrens@xxxxxx Latest working kernel version: 2.6.22 Earliest failing kernel version: 2.6.24 Distribution: Ubuntu 8.04 with vanilla kernel Hardware Environment: Fujitsu/Siemens Amilo Laptop Problem Description: When reading a few hundred MB from cdrom using DMA, kernel panics eventually. There are two setups WITHOUT this bug: - older kernels (where the cdrom gets mounted as hdc) - current kernels with libata.dma=1 (PIO4 mode ATAPI) Steps to reproduce: $ cp /media/cdromName/1-gb-file /home/onDisk After a few hundred MB, hard lockup: no LEDs, no SysRq, no logs. netconsole gave me the following output: [ 525.388025] divide error: 0000 [#1] SMP [ 525.388025] Modules linked in: netconsole configfs isofs binfmt_misc radeon drm rfcomm l2cap bluetooth ppdev powernow_k7 cpufreq_userspace cpufreq_stats cpufreq_powersave cpufreq_ondemand freq_table cpufreq_conservative video output sbs sbshc container iptable_filter ip_tables x_tables sbp2 lp ipv6 joydev tulip pcmcia serio_raw psmouse parport_pc parport pcspkr pwc videodev v4l1_compat i2c_viapro i2c_core via_ircc battery irda ac crc_ccitt yenta_socket button via_agp agpgart rsrc_nonstatic pcmcia_core shpchp pci_hotplug evdev ext3 jbd mbcache sg sr_mod cdrom sd_mod pata_via pata_acpi ata_generic libata via_rhine mii ehci_hcd uhci_hcd scsi_mod dock ohci1394 usbcore ieee1394 thermal processor fan thermal_sys fuse [ 525.388025] [ 525.388025] Pid: 6084, comm: trackerd Not tainted (2.6.26.3 #2) [ 525.388025] EIP: 0060:[<c0103d3c>] EFLAGS: 00200202 CPU: 0 [ 525.388025] EIP is at sysenter_past_esp+0x39/0xb1 [ 525.388025] EAX: 0000008c EBX: 0000001e ECX: 00000000 EDX: 000000d8 [ 525.388025] ESI: b7959bb0 EDI: 00000000 EBP: b7959b90 ESP: d9391fb8 [ 525.388025] DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 [ 525.388025] Process trackerd (pid: 6084, ti=d9390000 task=d9fba3f0 task.ti=d9390000) [ 525.388025] Stack: 0000001e 00000000 000f0000 b7959bb0 00000000 b7959b90 0000008c 0000007b [ 525.388025] 0000007b 00000000 0000008c b7f1b424 00000073 00200292 b7959b90 0000007b [ 525.388025] 00008067 00007067 [ 525.388025] Call Trace: [ 525.388025] ======================= [ 525.388025] Code: b4 24 34 e0 ff ff 50 fc 0f a0 06 1e 50 55 57 56 52 51 53 ba 7b 00 00 00 8e da 8e c2 ba d8 00 00 00 8e e2 fb 8d 04 05 00 00 00 00 <90> 8d 80 00 00 00 00 81 fd fd ff ff bf 0f 83 fa 01 00 00 8b 6d [ 525.388025] EIP: [<c0103d3c>] sysenter_past_esp+0x39/0xb1 SS:ESP 0068:d9391fb8 [ 525.388025] ---[ end trace 5028e900103372a1 ]--- [ 525.399790] divide error: 0000 [#2] SMP [ 525.399790] Modules linked in: netconsole configfs isofs binfmt_misc radeon drm rfcomm l2cap bluetooth ppdev powernow_k7 cpufreq_userspace cpufreq_stats cpufreq_powersave cpufreq_ondemand freq_table cpufreq_conservative video output sbs sbshc container iptable_filter ip_tables x_tables sbp2 lp ipv6 joydev tulip pcmcia serio_raw psmouse parport_pc parport pcspkr pwc videodev v4l1_compat i2c_viapro i2c_core via_ircc battery irda ac crc_ccitt yenta_socket button via_agp agpgart rsrc_nonstatic pcmcia_core shpchp pci_hotplug evdev ext3 jbd mbcache sg sr_mod cdrom sd_mod pata_via pata_acpi ata_generic libata via_rhine mii ehci_hcd uhci_hcd scsi_mod dock ohci1394 usbcore ieee1394 thermal processor fan thermal_sys fuse [ 525.399790] [ 525.399790] Pid: 0, comm: swapper Tainted: G D (2.6.26.3 #2) [ 525.399790] EIP: 0060:[<e081d2ae>] EFLAGS: 00000292 CPU: 0 [ 525.399790] EIP is at acpi_idle_enter_simple+0x16f/0x1dd [processor] [ 525.399790] EAX: c0479170 EBX: d5650000 ECX: 00006767 EDX: 00f8f000 [ 525.399790] ESI: d5650450 EDI: 001c3383 EBP: 001b8f17 ESP: c041ffac [ 525.399790] DS: 007b ES: 007b FS: 00d8 GS: 0000 SS: 0068 [ 525.399790] Process swapper (pid: 0, ti=c041e000 task=c03f0340 task.ti=c041e000) [ 525.399790] Stack: 0000a46c 00000000 d56500cc d56500dc d565001c 00922007 c0288c9a c0288c10 [ 525.399790] 00000000 c047c480 c0102753 00000000 00099800 c040f000 c04239ef 00000035 [ 525.399790] c0423130 00000000 c044e900 00000000 00000000 [ 525.399790] Call Trace: [ 525.399790] [<c0288c9a>] cpuidle_idle_call+0x8a/0xd0 [ 525.399790] [<c0288c10>] cpuidle_idle_call+0x0/0xd0 [ 525.399790] [<c0102753>] cpu_idle+0x63/0xe0 [ 525.399790] ======================= [ 525.399790] Code: 8d 04 07 99 89 04 24 b8 17 01 00 00 89 54 24 04 f7 24 24 69 4c 24 04 17 01 00 00 8d 14 11 e8 7a 15 92 df fb 8d 04 05 00 00 00 00 <90> 90 89 e0 31 c9 25 00 e0 ff ff 89 f2 83 48 0c 02 89 d8 ff 46 [ 525.399790] EIP: [<e081d2ae>] acpi_idle_enter_simple+0x16f/0x1dd [processor] SS:ESP 0068:c041ffac [ 525.399790] ---[ end trace 5028e900103372a1 ]--- [ 525.399790] Kernel panic - not syncing: Attempted to kill the idle task! $ lspci 00:00.0 Host bridge: VIA Technologies, Inc.
