Summary: PME never re-enabled for additional PCI buses (Asrock M3A785GXH/128M) Product: ACPI Version: 2.5 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Power-Sleep-Wake AssignedTo: acpi_power-sleep-w...@kernel-bugs.osdl.org ReportedBy: bl...@debian.org Regression: No Created an attachment (id=72060) --> (https://bugzilla.kernel.org/attachment.cgi?id=72060) kernel logs, default vs. pci=noapic Hello, my problem began with Wake-On-Lan issues, i.e. it never(*) really worked with Linux. The onboard NIC didn't work and and an extra NIC also failed (both configs worked perfectly with Windows 7, btw.). All the usual tipps (ethtool -g in suspend scripts, etc.) did not help. Finally I discovered something weird in the ACPI wakeup list, many devices were not present in the list of pciids, and I was also not able to re-enable them with "acpitool -W ..." or by sending values to related 'wakeup' files in sysfs. This leads to a closer examination of PCI configuration of this system, and I see that with pci=noapic, there is a late event which re-enables PME for NICs on additional PCI busses (0000:00:02.0, 0000:01:00.0). But with the default config, this never happens (see attachments). I added the log files for the particular starts. Created with 3.2-rc7 but the same happens with 3.2 and also happened with latest 2.6.x kernels, as far as I remember. My best idea so far was checking DSDT and recompiling it, and it displayed a lot of errors. Maybe it's just a conincidence, maybe not, any hint is appreciated. (*) the only time I used WOL on this system before was back in 2009 and that was with TuxOnIce patch and using real system shutdown and not ACPI S4. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ RSA(R) Conference 2012 Mar 27 - Feb 2 Save $400 by Jan. 27 Register now! http://p.sf.net/sfu/rsa-sfdev2dev2 _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
