cleaned bug description, moved the lines into here in case somebody is searching for the commands
in the debian bug record a simple verification can be found 1) find pci device codes for IDE and SATA controllers with lspci -nn part of the output on my machine: ... 00:1f.1 IDE interface [0101]: Intel Corporation 82801EB/ER (ICH5/ICH5R) IDE Controller [8086:24db] (rev 02) 00:1f.2 IDE interface [0101]: Intel Corporation 82801EB (ICH5) SATA Controller [8086:24d1] (rev 02) .... 2) search for SATA device codes in modules.pcimap for both kernels: on my machine: kernel 2.6.20-16: [EMAIL PROTECTED]:/lib/modules/2.6.20-16-generic$ grep "24d1" modules.pcimap piix 0x00008086 0x000024d1 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0 ata_piix 0x00008086 0x000024d1 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0 kernel 2.6.20-15 [EMAIL PROTECTED]:/lib/modules/2.6.20-15-generic$ grep "24d1" modules.pcimap ata_piix 0x00008086 0x000024d1 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0 ** Description changed: Binary package hint: linux-image-2.6.20-16-generic linux-image-2.6.20-15-generic worked fine with following system: feisty, xfs root fs (all in one) on (single) SATA disk on an intel ICH5 SATA controller (I965 chipset) after upgrading to linux-image-2.6.20-16-generic, the SATA disk is no more under control of ata_piix, which is not loaded anymore, SATA disk becomes /dev/hdc (/dev/hda being the DVD drive) instead of /dev/sda as with 2.6.20-15 - with boot option "irqpoll" I was able to save dmesg and lsmod outputs, - without "irqpoll" option, boot fails, even into single user mode. - - -------------------------------------- + with boot option "irqpoll" I was able to save dmesg and lsmod outputs, without "irqpoll" option, boot fails, even into single user mode. + -------------------------- klmonz 2007-05-31 this bug is already described well in debian bug # 419458 [ http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=419458 ] - which is already fixed in a new kernel package (for debian, NOT ubuntu!) + with 2.6.20-16 the SATA controller is claimed by both piix (IDE driver) and ata_piix (SATA driver) - in the debian bug record a simple verification can be found - 1) find pci device codes for IDE and SATA controllers with - lspci -nn - part of the output on my machine: - ... - 00:1f.1 IDE interface [0101]: Intel Corporation 82801EB/ER (ICH5/ICH5R) IDE Controller [8086:24db] (rev 02) - 00:1f.2 IDE interface [0101]: Intel Corporation 82801EB (ICH5) SATA Controller [8086:24d1] (rev 02) - .... - - 2) search for SATA device codes in modules.pcimap for both kernels: - on my machine: - kernel 2.6.20-16: - [EMAIL PROTECTED]:/lib/modules/2.6.20-16-generic$ grep "24d1" modules.pcimap - piix 0x00008086 0x000024d1 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0 - ata_piix 0x00008086 0x000024d1 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0 - - kernel 2.6.20-15 - [EMAIL PROTECTED]:/lib/modules/2.6.20-15-generic$ grep "24d1" modules.pcimap - ata_piix 0x00008086 0x000024d1 0xffffffff 0xffffffff 0x00000000 0x00000000 0x0 - - so it is obvious that with 2.6.20-16 the SATA controller is claimed by both piix (IDE driver) and ata_piix (SATA driver); - that's where the problem arises. - - So I would hope some ubuntu kernel guru would take a closer look onto - this now (how to trigger this? I'm afraid there's a lot of stuff coming - in here every day...) - - ***** - sorry for updating that often, I kept typing nonsense/mistakes :-| + details how to identify this are given in comment 72 down here (from the + debian bug record) -- SATA disk is in PATA mode with kernel 2.6.20-16-generic (piix claiming SATA controller on ICH4/ICH5 Intel chipsets) https://bugs.launchpad.net/bugs/116996 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
