From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7b) Gecko/20040319 Description of problem: test kernels after 2.6.6-1.383 do not resume from ACPI S3 diffs from the sources show patches to pci_driver.c that may be involved. But I no longer have access to the kernel sources immediately following 2.6.6-1.383. Is there an archive of these? NB this chipset (Intel 82443BX) has known bugs with the memory refresh state machine and suspend that may have an workaround in the BIOS for APM but not for ACPI. See Intel update 29063906 (Errata 12). I am also seeing strange behaviour from the BIOS, ACPI drivers and the sound driver (maestro3) relating to resume. - from initial boot to first suspend, the BIOS keys for display brightness and BIOS version/battery overlay work; after resume they do nothing - rmmod ac and battery before suspend seems to improve the success rate of resume to near 100% on the 2.6.6-1.383 kernel. - rmmod/suspend/modprobe ac and battery is needed to make the drivers report the battery information (otherwise it is 'not present') - from initial boot to first suspend, no sounds are heard; after resume the sound works normally Version-Release number of selected component (if applicable): kernel > 2.6.6-1.383 How reproducible: Always Steps to Reproduce: 1. boot kernel more recent than 2.6.6-1.383 2. suspend the machine using ACPI 3. attempt to resume Actual Results: machine hangs while unsuspending - there may be some disk activity or the screen may turn on before hanging Expected Results: successful resume Additional info: Pentium III Coppermine Machine info from 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 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 03)
fixed! 2.6.6-1.414 will suspend again. Although the BIOS functionality is still disconnected by the suspend/resume cycle
