Gareth, I have finally tried some of the options proposed at http://linux-ata.org/faq.html#combined
At the time you sent the email I was not experiencing lockups, but since kernel 2.6.24 in Hardy I have problems every few hours (I suspect 2.6.24 being particularly problematic, as it causes a "kernel NULL reference" Oops on my other machine, but that's the object of a separate bug report). So far I looked at: - BIOS settings: Recommended (where BIOS permits): Change BIOS IDE mode from "legacy" or "combined" mode to "AHCI" (recommended), "RAID" or "native". Nothing indicated on the page is possible with my BIOS - kernel parameters: Boot with the kernel commandline parameter "combined_mode=libata" or "combined_mode=ide" to allow the specified driver to claim all IDE ports. No real effect when applying either of libata or ide. Still locks up :/ Thanks, L. 2008/3/13, Gareth Fitzworthington <[EMAIL PROTECTED]>: > OK. > Yes, if you are able, try the SATA/PATA combination test.

The symptoms are generally: 1- freeze on X 2- if quick enough, I can switch to a console (Ctrl + F*) 3- trying to log on the console prompts error messages like "ata2: speed down requests" "Error sending Cmd #07" "Write error on swap device", etc... The systems never get to log me in 4- trying to access the computer remotely is unsuccessful (the machine does not answer anymore) 5- only a hard reboot is possible /var/log/messages contains the following during normal operations Mar 3 10:30:23 hot-spring kernel: [ 1810.944000] ata2.00: limiting speed to PIO2 Mar 3 10:30:23 hot-spring kernel: [ 1810.944000] res 40/00:03:00:00:00/00:00:00:00:00/a0 Emask 0x4 (timeout) Mar 3 10:30:30 hot-spring kernel: [ 1817.948000] ata2: port is slow to respond, please be patient (Status 0xd0) Mar 3 10:30:53 hot-spring kernel: [ 1840.964000] ata2: soft resetting port Mar 3 10:30:54 hot-spring kernel: [ 1841.300000] ACPI Error (dsopcode-0481): Attempt to CreateField of length zero [20060707] Mar 3 10:30:54 hot-spring kernel: [ 1841.300000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.IDE0.RATA] (Node df994770), AE_AML_OPERAND_VALUE Mar 3 10:30:54 hot-spring kernel: [ 1841.300000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.IDE0.CHN1.DRV0._GTF] (Node df9948c4), AE_AML_OPERAND_VALUE Mar 3 10:30:54 hot-spring kernel: [ 1841.492000] ACPI Error (dsopcode-0481): Attempt to CreateField of length zero [20060707] Mar 3 10:30:54 hot-spring kernel: [ 1841.492000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.IDE0.RATA] (Node df994770), AE_AML_OPERAND_VALUE Mar 3 10:30:54 hot-spring kernel: [ 1841.492000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.IDE0.CHN1.DRV0._GTF] (Node df9948c4), AE_AML_OPERAND_VALUE Mar 3 10:30:54 hot-spring kernel: [ 1841.492000] ata2.00: configured for PIO2 Mar 3 10:30:54 hot-spring kernel: [ 1841.492000] ata2: EH complete Mar 3 10:32:20 hot-spring kernel: [ 1927.576000] ata2.00: limiting speed to PIO1 Mar 3 10:32:20 hot-spring kernel: [ 1927.576000] res 40/00:03:00:00:00/00:00:00:00:00/a0 Emask 0x4 (timeout) Mar 3 10:32:27 hot-spring kernel: [ 1934.584000] ata2: port is slow to respond, please be patient (Status 0xd0) Mar 3 10:32:50 hot-spring kernel: [ 1957.600000] ata2: soft resetting port Mar 3 10:32:50 hot-spring kernel: [ 1957.944000] ACPI Error (dsopcode-0481): Attempt to CreateField of length zero [20060707] Mar 3 10:32:50 hot-spring kernel: [ 1957.944000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.IDE0.RATA] (Node df994770), AE_AML_OPERAND_VALUE Mar 3 10:32:50 hot-spring kernel: [ 1957.944000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.IDE0.CHN1.DRV0._GTF] (Node df9948c4), AE_AML_OPERAND_VALUE Mar 3 10:32:50 hot-spring kernel: [ 1958.136000] ACPI Error (dsopcode-0481): Attempt to CreateField of length zero [20060707] Mar 3 10:32:50 hot-spring kernel: [ 1958.136000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.IDE0.RATA] (Node df994770), AE_AML_OPERAND_VALUE Mar 3 10:32:50 hot-spring kernel: [ 1958.136000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.IDE0.CHN1.DRV0._GTF] (Node df9948c4), AE_AML_OPERAND_VALUE Mar 3 10:32:50 hot-spring kernel: [ 1958.136000] ata2.00: configured for PIO1 Mar 3 10:32:50 hot-spring kernel: [ 1958.136000] ata2: EH complete Mar 3 10:34:52 hot-spring kernel: [ 2079.484000] ata2.00: limiting speed to PIO0 Mar 3 10:34:52 hot-spring kernel: [ 2079.484000] res 40/00:03:00:00:00/00:00:00:00:00/a0 Emask 0x4 (timeout) Mar 3 10:34:59 hot-spring kernel: [ 2086.488000] ata2: port is slow to respond, please be patient (Status 0xd0) Mar 3 10:35:22 hot-spring kernel: [ 2109.504000] ata2: soft resetting port Mar 3 10:35:22 hot-spring kernel: [ 2109.848000] ACPI Error (dsopcode-0481): Attempt to CreateField of length zero [20060707] Mar 3 10:35:22 hot-spring kernel: [ 2109.848000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.IDE0.RATA] (Node df994770), AE_AML_OPERAND_VALUE Mar 3 10:35:22 hot-spring kernel: [ 2109.848000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.IDE0.CHN1.DRV0._GTF] (Node df9948c4), AE_AML_OPERAND_VALUE Mar 3 10:35:22 hot-spring kernel: [ 2110.040000] ACPI Error (dsopcode-0481): Attempt to CreateField of length zero [20060707] Mar 3 10:35:22 hot-spring kernel: [ 2110.040000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.IDE0.RATA] (Node df994770), AE_AML_OPERAND_VALUE Mar 3 10:35:22 hot-spring kernel: [ 2110.040000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.IDE0.CHN1.DRV0._GTF] (Node df9948c4), AE_AML_OPERAND_VALUE Mar 3 10:35:22 hot-spring kernel: [ 2110.040000] ata2.00: configured for PIO0 Mar 3 10:35:22 hot-spring kernel: [ 2110.040000] ata2: EH complete -- system locking up (forcing a hard reboot) https://bugs.launchpad.net/bugs/89362 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
