Bug#598518: linux-image-2.6-686: ata_piix module loaded before ahci module deactivate hotplug support (regression from lenny)
2010/10/20 Thomas DEBESSE thomas.debesse+deb...@gmail.com: I've just installed a fresh Squeeze and I got the new kernel : I have the 2.6.32-25, wich was announced to solve the problem, and yes this new one put modules.order in initramfs but the wrong module is always loaded : This bug is not fixed. The previous test was done with a livecd installing 2.6.32-24 then upgrading to 2.6.32-25. I've done another test with another fresh install but using a livecd with 2.6.32-25 kernel. The good module is loaded without modifying aliases.conf. This bug seems fixed, but there is some persistence when upgrading from previously installed Squeeze distros.

Ben Hutchings b...@decadent.org.uk: modules.order is generated during the kernel build process and will be copied into the initramfs by update-initramfs if present. However, we currently delete modules.* when creating the image packages, because we assume all those files are generated by depmod. Oops. dann frazier da...@debian.org: We believe that the bug you reported is fixed in the latest version of linux-2.6, which is due to be installed in the Debian FTP archive: linux-headers-2.6.32-5-686_2.6.32-25_i386.deb to main/l/linux-2.6/linux-headers-2.6.32-5-686_2.6.32-25_i386.deb I've just installed a fresh Squeeze and I got the new kernel : # apt-cache show linux-image-2.6.32-5-686 | grep ^Version Version: 2.6.32-25 I have the 2.6.32-25, wich was announced to solve the problem, and yes this new one put modules.order in initramfs # gunzip initrd.img-2.6.32-5-686 | cpio -i --make-directories 45807 blocs # find . -iname *module* ./lib/modules ./lib/modules/2.6.32-5-686/modules.softdep ./lib/modules/2.6.32-5-686/modules.symbols ./lib/modules/2.6.32-5-686/modules.symbols.bin ./lib/modules/2.6.32-5-686/modules.order ./lib/modules/2.6.32-5-686/modules.alias ./lib/modules/2.6.32-5-686/modules.dep ./lib/modules/2.6.32-5-686/modules.dep.bin ./lib/modules/2.6.32-5-686/modules.devname ./lib/modules/2.6.32-5-686/modules.alias.bin ./conf/modules and ahci module appear before ata_piix in modules.order # grep 'ahci\|ata_piix' ./lib/modules/2.6.32-5-686/modules.order kernel/drivers/ata/ahci.ko kernel/drivers/ata/ata_piix.ko but the wrong module is always loaded : # lspci -vvv -s 00:1f.2 | grep 'SATA\|Kernel driver' 00:1f.2 SATA controller: Intel Corporation 82801FR/FRW (ICH6R/ICH6RW) SATA Controller (rev 03) (prog-if 01 [AHCI 1.0]) Kernel driver in use: ata_piix modules.order does'nt change anything.

With Lenny, the job of knowing that two modules could be used, knowing that one is better than another and choosing the good one is done by software. With Squeeze, this job is done by man... Perhaps the bug is not related to the linux-image package, but a collateral damage of another package ?

Package: linux-image-2.6-686 Version: 2.6.32+28 Severity: important ICH6 sata controller could be managed by both ata_piix and ahci module but only ahci module handle hotplug. At boot time, when ata_piix is loaded before ahci module, it takes control of the ICH6 controller and the ahci module does'nt manage nothing. Because ata_piix also manage ICH6 sata controller, hard drives are managed, but because ata_piix module is used in place of ahci module, because ahci module is'nt used, hotplug (and other ahci functionnalities indeed) does'nt works. On both Lenny and Squeeze linux kernels I've the two modules (ahci and ata_piix) loaded, but on Lenny this is the fully functionnal ahci module which is use, and on Squeeze this is the limited ata_piix module which is used. here the lspci -vv on Lenny and Squeeze : # lspci -vv -s 00:1f.2 | tee lspci-lenny 00:1f.2 SATA controller: Intel Corporation 82801FR/FRW (ICH6R/ICH6RW) SATA Controller (rev 03) (prog-if 01 [AHCI 1.0]) Subsystem: Super Micro Computer Inc Device 6280 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=medium TAbort- TAbort- MAbort- SERR- PERR- INTx- Latency: 0 Interrupt: pin B routed to IRQ 19 Region 0: I/O ports at e900 [size=8] Region 1: I/O ports at ea00 [size=4] Region 2: I/O ports at eb00 [size=8] Region 3: I/O ports at ec00 [size=4] Region 4: I/O ports at ed00 [size=16] Region 5: Memory at d03c3000 (32-bit, non-prefetchable) [size=1K] Capabilities: [70] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot+,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME- Kernel driver in use: ahci Kernel modules: ahci, ata_piix # lspci -vv -s 00:1f.2 | tee lspci-squeeze 00:1f.2 SATA controller: Intel Corporation 82801FR/FRW (ICH6R/ICH6RW) SATA Controller (rev 03) (prog-if 01 [AHCI 1.0]) Subsystem: Super Micro Computer Inc Device 6280 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=medium TAbort- TAbort- MAbort- SERR- PERR- INTx- Latency: 0 Interrupt: pin B routed to IRQ 19 Region 0: I/O ports at e900 [size=8] Region 1: I/O ports at ea00 [size=4] Region 2: I/O ports at eb00 [size=8] Region 3: I/O ports at ec00 [size=4] Region 4: I/O ports at ed00 [size=16] Region 5: Memory at d03c3000 (32-bit, non-prefetchable) [size=1K] Capabilities: [70] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot+,D3cold-) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Kernel driver in use: ata_piix you can see the problem : # diff lspci-lenny lspci-squeeze 16,18c16,17 Status: D0 PME-Enable- DSel=0 DScale=0 PME- Kernel driver in use: ahci Kernel modules: ahci, ata_piix --- Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Kernel driver in use: ata_piix I can't blacklist ata_piix module, because is needed for IDE drives (like CD drive) The solution is to load ahci module before ata_piix module, then we can have SATA drives managed by ahci module and IDE drives managed by ata_piix module.
