I'm running kernel 2.6.9 no apic no acpi fully preentible on a Slackware 10 with udev-040 ,hotplug 2004_09_23 and module-init-tools-3.0 I can reproduce a oops when I try, after unmounting the device, to disconnect or power off a Plextor PX-W4824 USB burner from a uhci_hcd host. When in X the machine hangs. My machine is a pentium 3 on a 440BX chipset.
No problem with kernel 2.6.7. lspci: 00:00.0 Host bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (rev 03) 00:01.0 PCI bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX AGP bridge (rev 03) 00:07.0 ISA bridge: Intel Corp. 82371AB/EB/MB PIIX4 ISA (rev 02) 00:07.1 IDE interface: Intel Corp. 82371AB/EB/MB PIIX4 IDE (rev 01) 00:07.2 USB Controller: Intel Corp. 82371AB/EB/MB PIIX4 USB (rev 01) 00:07.3 Bridge: Intel Corp. 82371AB/EB/MB PIIX4 ACPI (rev 02) 00:0b.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 78) 00:0d.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 78) 00:0f.0 Multimedia audio controller: IC Ensemble Inc ICE1712 [Envy24] (rev 02) 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV200 QW [Radeon 7500] the error: Oct 19 17:59:46 chopin kernel: sr 0:0:0:0: Illegal state transition cancel->offline Oct 19 17:59:46 chopin kernel: Badness in scsi_device_set_state at drivers/scsi/scsi_lib.c:1688 Oct 19 17:59:46 chopin kernel: [<c896bcc9>] scsi_device_set_state +0xc9/0x120 [scsi_mod] Oct 19 17:59:46 chopin kernel: [<c89699ae>] scsi_eh_offline_sdevs +0x6e/0x90 [scsi_mod] Oct 19 17:59:46 chopin kernel: [<c8969e83>] scsi_unjam_host+0xc3/0xd0 [scsi_mod] Oct 19 17:59:46 chopin kernel: [<c8969f38>] scsi_error_handler +0xa8/0xd0 [scsi_mod] Oct 19 17:59:46 chopin kernel: [<c8969e90>] scsi_error_handler+0x0/0xd0 [scsi_mod] Oct 19 17:59:46 chopin kernel: [<c01023bd>] kernel_thread_helper +0x5/0x18 Oct 19 17:59:46 chopin kernel: Unable to handle kernel paging request at virtual address 5f6c656e Oct 19 17:59:46 chopin kernel: printing eip: Oct 19 17:59:46 chopin kernel: c02281f3 Oct 19 17:59:46 chopin kernel: *pde = 00000000 Oct 19 17:59:46 chopin kernel: Oops: 0000 [#1] Oct 19 17:59:46 chopin kernel: PREEMPT Oct 19 17:59:46 chopin kernel: Modules linked in: nls_utf8 isofs nls_base sr_mod usb_storage scsi_mod snd_ice1712 snd_ice17xx_ak4xxx snd_pcm snd_timer snd_page_alloc snd_ak4xxx_adda snd_cs8427 snd_ac97_codec snd_i2c snd_mpu401_uart snd_rawmidi snd soundcore usbhid 3c59x uhci_hcd usbcore intel_agp agpgart rtc Oct 19 17:59:46 chopin kernel: CPU: 0 Oct 19 17:59:46 chopin kernel: EIP: 0060:[<c02281f3>] Not tainted VLI Oct 19 17:59:46 chopin kernel: EFLAGS: 00010083 (2.6.9) Oct 19 17:59:46 chopin kernel: EIP is at as_requeue_request+0x93/0xf0 Oct 19 17:59:46 chopin kernel: eax: 5f6c656e ebx: 00000000 ecx: c7e50028 edx: c7f048b0 Oct 19 17:59:46 chopin kernel: esi: c7f048b0 edi: c7fd7740 ebp: 00000202 esp: c3895f04 Oct 19 17:59:46 chopin kernel: ds: 007b es: 007b ss: 0068 Oct 19 17:59:46 chopin kernel: Process scsi_eh_0 (pid: 3130, threadinfo=c3894000 task=c7b94020) Oct 19 17:59:46 chopin kernel: Stack: 00000000 c010479d 00000000 c01023bd c7f048b0 c3bb4040 c7e50028 c021f846 Oct 19 17:59:46 chopin kernel: c7e50028 c7f048b0 c7f048b0 c3bb4040 c02221cd c7e50028 c7f048b0 c7b94020 Oct 19 17:59:46 chopin kernel: 00000286 c7a08800 c3bb4040 c7fd0a00 00001057 c896a247 c7e50028 c7f048b0 Oct 19 17:59:46 chopin kernel: Call Trace: Oct 19 17:59:46 chopin kernel: [<c010479d>] print_context_stack +0x2d/0x70 Oct 19 17:59:46 chopin kernel: [<c01023bd>] kernel_thread_helper +0x5/0x18 Oct 19 17:59:46 chopin kernel: [<c021f846>] elv_requeue_request +0x26/0x60 Oct 19 17:59:46 chopin kernel: [<c02221cd>] blk_insert_request +0xdd/0xe0 Oct 19 17:59:46 chopin kernel: [<c896a247>] scsi_queue_insert+0x77/0xb0 [scsi_mod] Oct 19 17:59:46 chopin kernel: [<c8969daf>] scsi_eh_flush_done_q +0x9f/0xb0 [scsi_mod] Oct 19 17:59:46 chopin kernel: [<c8969e4f>] scsi_unjam_host+0x8f/0xd0 [scsi_mod] Oct 19 17:59:46 chopin kernel: [<c8969f38>] scsi_error_handler +0xa8/0xd0 [scsi_mod] Oct 19 17:59:46 chopin kernel: [<c8969e90>] scsi_error_handler+0x0/0xd0 [scsi_mod] Oct 19 17:59:46 chopin kernel: [<c01023bd>] kernel_thread_helper +0x5/0x18 Oct 19 17:59:46 chopin kernel: Code: ff c7 43 38 02 00 00 00 8b 43 18 85 c0 74 19 8b 40 10 85 c0 74 12 ff 40 10 eb 0d 90 90 90 90 90 90 90 90 90 90 90 90 90 8b 47 2c <8b> 10 89 72 04 89 16 89 46 04 89 30 8b 5c 24 10 89 7c 24 20 8b Oct 19 17:59:46 chopin kernel: <6>note: scsi_eh_0[3130] exited with preempt_count 1 ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
