It seems it hit the same bug (latest intrepid, Sony Vaio BZ11XN + Intel GMA X4500MHD, HW info located @ http://deep-ocean.net/files/sony) : - when I suspend, everything seems fine ; the machine shuts down and the yellow led starts blinking. - on resume, all kbd leds blink one time (kbd reset i presume), the LCD goes on (only backlight), disk led blinks a little, LCD goes off then back on with X cursor, - but the X cursor is stuck. caps lock doesn't work, sysrq doesn't work. only solution is 4-seconds press on power off (no reset button on my vaio).
This has happened from Intrepid kernel 2.6.27-3. I followed https://wiki.ubuntu.com/DebuggingKernelSuspend, did the suspend/resume cycle with and without external usb devices pluged in, and only got (every time) : [ 4.723037] Magic number: 0:953:373 [ 4.723096] hash matches /build/buildd/linux-2.6.27/drivers/base/power/main.c:390 No more "hash matches" when getting dmesg from a recovery boot just after the power-off following the kernel freeze. - I didn't test previous Intrepid 2.6.26 yet. - I didn't test on hardy because this hardware is very recent and there isn't video support in xorg for my card in hardy. - i didn't test to put a "touch" in every pm-files, but as suggested by jason, this will not help that much. - i will test with drm kernel module blacklisted (next thing to do to confirm this is the same exact bug). - i will try to recompile a kernel with ACPI_DEBUG=y, but i haven't compiled a kernel for years (thanks to ubuntu, i didn't touch xorg.conf for years too… ;-) ), this will take a little time. Any more advice on how to nail down the problem ? I know without the kernel oops this is kind of stunning difficulty, but i'd be happy to provide this oops because suspend/resume is kind of important feature for me. -- DRM Breaks Resume from Suspend https://bugs.launchpad.net/bugs/274278 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
