I have similiar problem on Acer Aspire 5512 laptop in 2.6.28-11-generic kernel. In 2.6.27-11-generic it is faster. Ubuntu 9.04 (official update), 32bit.
It seems to be some kind related to input / mouse / touchpad or paraller port (i dont have any paralel port in laptop). dmesg (2.6.28-11-generic): [ 15.192123] Synaptics Touchpad, model: 1, fw: 6.2, id: 0x12a0b1, caps: 0xa04713/0x204000 [ 15.224020] intel8x0_measure_ac97_clock: measured 54027 usecs [ 15.224022] intel8x0: clocking to 48000 [ 15.227815] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input10 [ 19.367548] synaptics: using relaxed packet validation [ 193.044195] lp: driver loaded but no devices found [ 193.115149] input: Acer hotkey driver as /devices/virtual/input/input11 [ 193.118750] acerhk: model string indicates unknown TM xxx series [ 193.119193] Acer Travelmate hotkey driver v0.5.34 dmesg (2.6.27-11-generic): [ 26.674737] saa7134 ALSA driver for DMA sound loaded [ 26.674773] saa7133[0]/alsa: saa7133[0] at 0xc8217800 irq 17 registered as card -2 [ 26.904023] intel8x0_measure_ac97_clock: measured 53976 usecs [ 26.904028] intel8x0: clocking to 48000 [ 27.069787] lp: driver loaded but no devices found [ 27.229588] input: Acer hotkey driver as /devices/virtual/input/input11 [ 27.234728] acerhk: model string indicates unknown TM xxx series [ 27.235176] Acer Travelmate hotkey driver v0.5.34 (there is no synaptics entry anywhere in dmesg) I included bootchart log (2 is 2.6.28 kernel, 3 is 2.6.27). ** Attachment added: "bootchart.tar.gz" http://launchpadlibrarian.net/26135876/bootchart.tar.gz -- Long delay during boot screen Jaunty AMD64 https://bugs.launchpad.net/bugs/355299 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
