[Bug 1262797] Re: [Acer Aspire 7740] acer-wmi module hangs laptop for 10 seconds on boot/modprobe
Tested on 12.04, and also hangs there BUT I found the 'cause' of it. When I received this laptop I installed a new half size mini PCIE wireless card (Intel based) and that seems to cause the hang somehow. When I remove the wireless card or reinstall the old original one modprobing acer-wmi finishes immediately and succesfull with no hangs. I don't know now if this is still a valid bug, since maybe the card is not fully supported by the laptop (while it works ok besides this issue). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1262797 Title: [Acer Aspire 7740] acer-wmi module hangs laptop for 10 seconds on boot/modprobe To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1262797/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

** Tags added: raring ** Description changed: - I have a Acer Aspire 7740, and noticed after installing that Ubuntu 13.10 (kernel 3.11.0-14) hangs for 10 seconds early in the boot process. It continues after that. + When I received this laptop I installed a new half size mini PCIE wireless card (Intel based) I noticed after installing that Ubuntu 13.10 (kernel 3.11.0-14) hangs for 10 seconds early in the boot process. It continues after that. The screen freezes and the fans start spinning very hard. The last dmesg line before the pause is a info message about acer-wmi. When modprobing this module after boot the same symptoms occur. Ubuntu hangs, and reacts normally after 10 seconds. So, clearly something is wrong with acer-wmi. Maybe it should not be loaded with this laptop version, or it has a bug in it. I will add a dmesg from a boot with acer-wmi enabled. - WORKAROUND: I blacklisted acer-wmi in /etc/modprobe.d/blacklist.conf and updated initramfs. Now ubuntu boots as it should without hanging. No functionality appears to be lost. Bluetooth and wifi work, also the volume keys. - --- + WORKAROUND: I blacklisted acer-wmi in /etc/modprobe.d/blacklist.conf and + updated initramfs.

[Bug 1262797] Re: [Acer Aspire 7740] acer-wmi module hangs laptop for 10 seconds on boot/modprobe
Peter de Kraker, thank you for performing the requested test and the follow up information. I briefly scanned acer-wmi and didn't see anything patently obvious code wise as to why this would occur with a non-OEM provided WiFi chip (although I'm not terribly familiar with it). Cursorily, the BIOS may have something hardcoded that depends on the original OEM hardware, which would make sense here. Despite this, what could be expected if it's not a BIOS bug, is a quirk of some sort that minimizes or eliminates the 10 second delay. Hence, the issue you are reporting is an upstream one. Could you please report this problem through the appropriate channel (I would start with platform-driver-x86 and CC Lee, Chun-Yi j...@suse.com) by following the instructions _verbatim_ at https://wiki.ubuntu.com/Bugs/Upstream/kernel#KernelTeam.2BAC8-KernelTeamBugPolicies.Overview_on_Reporting_Bugs_Upstream ? Please provide a direct URL to your post once you have made it so that it may be tracked.
