2.6.13.4 DMesg Ouput
dmesg output 2.6.13.2 |
||
Do you have any patches applied to your kernel or is it a vanilla ftp.kernel.org kernel? Am I understanding you correctly that 2.6.13.2 works and 2.6.13.4 doesn't work? Please attach complete dmesg for both kernels. No patches have been applied to any kernels. All are pure vanilla from Kernel.org. I haven't been able to see the CDR/DVDROM after 2.6.13.2.

2.6.13.4 DMesg Ouput
This is the dmesg output taken direction off of a fresh boot into the kernel
2.6.13.4
Created attachment 6443 [details]
dmesg output 2.6.13.2
here is the dmesg output from the 2.6.13.2 taken immediately after boot into
system
Sorry, my fault: Please attach in both cases the output of dmesg -s 1000000 This will hopefully show the interesting stuff. This looks like a .config problem - perhaps something changed in scsi and your modules aren't being built. Do you actually have an sr_mod.ko and sd_mod.ko under /lib/modules/2.6.14/kernel/drivers/... ? Anyway, check the .config and if it's still happening, we might have a module dependency problem. looks like the modules are there. i have sd_mod compiled into the kernel. cody@cooter:/lib/modules/2.6.14.1.20051110.1/kernel/drivers/scsi$ ls sg.ko sr_mod.ko looks like sr_mod is being loaded: here my lsmod... cooter:~# lsmod Module Size Used by af_packet 18184 2 binfmt_misc 9736 1 thermal 10888 0 fan 3460 0 button 5008 0 processor 14508 1 thermal ac 3460 0 battery 7684 0 pcmcia 33428 2 firmware_class 8448 1 pcmcia ohci1394 33332 0 yenta_socket 25100 2 rsrc_nonstatic 10368 1 yenta_socket pcmcia_core 37648 3 pcmcia,yenta_socket,rsrc_nonstatic 8250_pci 18176 0 8250 22116 1 8250_pci serial_core 19328 1 8250 snd_intel8x0 31456 1 snd_ac97_codec 95740 1 snd_intel8x0 snd_ac97_bus 2048 1 snd_ac97_codec snd_pcm_oss 51360 1 snd_mixer_oss 18048 1 snd_pcm_oss snd_pcm 85640 3 snd_intel8x0,snd_ac97_codec,snd_pcm_oss snd_timer 22788 1 snd_pcm snd 48356 6 snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer soundcore 8288 2 snd snd_page_alloc 8712 2 snd_intel8x0,snd_pcm ehci_hcd 31496 0 usbhid 36960 0 uhci_hcd 31888 0 usbcore 112896 4 ehci_hcd,usbhid,uhci_hcd intel_agp 21276 1 agpgart 29896 1 intel_agp rtc 11320 0 sg 35616 0 sr_mod 14500 0 cdrom 38688 1 sr_mod sbp2 22020 0 ieee1394 292152 2 ohci1394,sbp2 b44 21252 0 mii 4864 1 b44 unix 25136 498 cooter:~# sr_mod is here. cooter:~# modinfo sr_mod filename: /lib/modules/2.6.14.1.20051110.1/kernel/drivers/scsi/sr_mod.ko license: GPL vermagic: 2.6.14.1.20051110.1 preempt PENTIUMM gcc-4.0 depends: cdrom parm: xa_test:int cooter:~# uname -a Linux cooter 2.6.14.1.20051110.1 #1 PREEMPT Thu Nov 10 10:39:45 CST 2005 i686 GNU/Linux cooter:~# i also did a diff of the .configs into two different kernel sources cooter:/usr/src# diff linux-2.6.13.2/.config linux-2.6.14.1/.config 3,4c3,4 < # Linux kernel version: 2.6.13.2 < # Tue Nov 1 11:33:22 2005 --- > # Linux kernel version: 2.6.14.1.20051110.1 > # Thu Nov 10 10:34:45 2005 6a7 > CONFIG_SEMAPHORE_SLEEPERS=y 10a12 > CONFIG_ARCH_MAY_HAVE_PC_FDC=y 24a27 > CONFIG_LOCALVERSION_AUTO=y 35a39 > CONFIG_INITRAMFS_SOURCE="" 134a139,140 > # CONFIG_DELL_RBU is not set > CONFIG_DCDBAS=m 143a150 > # CONFIG_SPARSEMEM_STATIC is not set 147d153 < CONFIG_HAVE_DEC_LOCK=y 169,170d174 < CONFIG_ACPI_BOOT=y < CONFIG_ACPI_INTERPRETER=y 185d188 < CONFIG_ACPI_BUS=y 188d190 < CONFIG_ACPI_PCI=y 196,203c198 < CONFIG_APM=m < # CONFIG_APM_IGNORE_USER_SUSPEND is not set < # CONFIG_APM_DO_ENABLE is not set < # CONFIG_APM_CPU_IDLE is not set < # CONFIG_APM_DISPLAY_BLANK is not set < # CONFIG_APM_RTC_IS_GMT is not set < # CONFIG_APM_ALLOW_INTS is not set < # CONFIG_APM_REAL_MODE_POWER_OFF is not set --- > # CONFIG_APM is not set 224d218 < CONFIG_PCI_NAMES=y 247d240 < # CONFIG_TCIC is not set 300,301c293,294 < CONFIG_IP_TCPDIAG=y < # CONFIG_IP_TCPDIAG_IPV6 is not set --- > CONFIG_INET_DIAG=y > CONFIG_INET_TCP_DIAG=y 340a334 > # CONFIG_NETFILTER_NETLINK is not set 347a342 > # CONFIG_IP_NF_CONNTRACK_EVENTS is not set 350a346 > # CONFIG_IP_NF_NETBIOS_NS is not set 352a349 > # CONFIG_IP_NF_PPTP is not set 376a374 > # CONFIG_IP_NF_MATCH_DCCP is not set 378a377 > # CONFIG_IP_NF_MATCH_STRING is not set 383a383 > # CONFIG_IP_NF_TARGET_NFQUEUE is not set 400a401 > # CONFIG_IP_NF_TARGET_TTL is not set 411a413,417 > # DCCP Configuration (EXPERIMENTAL) > # > # CONFIG_IP_DCCP is not set > > # 436a443 > # CONFIG_IEEE80211 is not set 450a458,462 > # Connector -

Thanks. Please reopen this bug if it's still present with kernel 2.6.22. |
Most recent kernel where this bug did not occur:2.6.13.2 Distribution: Debian Etch Hardware Environment: Dell Inspiron 6000 Laptop Pentium M Software Environment: Problem Description: Kernel doesn't recognize cd-r/dev-rom in kernels after 2.6.13.2 using SCSI loadable module. Output on /val/log/boot in 2.6.13.2: Tue Nov 1 13:05:20 2005: scsi Tue Nov 1 13:05:20 2005: sd_mod: can't be loaded (for disk) Tue Nov 1 13:05:20 2005: sr_mod: loaded successfully (for cdrom) Tue Nov 1 13:05:20 2005: sg: loaded successfully (for cdrom) Tue Nov 1 13:05:20 2005: scsi [success] /var/log/boot output after: scsi sd_mod: can't be loaded (for disk) scsi [success] Steps to reproduce: I am using identical .configs in each vanilla source from kernel.org. Copy .config from 13.2 to 13.4 -- using make oldconfig. Same issue happens with 2.6.14
