[Bug 1616695] [NEW] Bluetooth signal is unusably poor
Public bug reported: Brand new Macbook Pro 12,1. Brand new Ubuntu 16.04 install (from scratch). In MacOS the machine can connect to my bluetooth speaker from across the room and play A2DP no trouble at all. In Ubuntu 16.04 I have to literally hold up the macbook 1 inch away from the speaker to get it to connect and play, and even then it's a bit choppy. Turning off Wifi seems to help a bit, which leads me to think this is some kind of transmit power issue.

@Andy -- I'm confused how this should work. This whole time we've been talking about an out-of-tree module. Does the kernel you posted contain that module built in somehow?

[Bug 585938] Re: [STAGING] r8192se_pci + powertop = kernel panic
1) I can confirm everything Matt has said so far on my machine. iwpriv -a is definitely the cause of the problem 2) Obviously I cant copy paste so good from a non-X vt on a machine that has had a kernel panic. I took a photo however (attached) 3) It looks like it crashes on an ioctl (surprise, surprise). Sadly the exact ioctl isnt there? It shows me ioctl(0x8bec) which looks like memory somehow got corrupted and its passing a bad ioctl?There is another suspicious ioctl before the crash without a macro mapping, 0x8be5. I'm going to try playing with some things, such as: making iwpriv a noop by converting to a bash script and seeing if that makes the system stable. Snooping around with iwpriv a bit more, maybe try some gdb break points, see if I can narrow this down further and come up with a patch (to either iwpriv or the driver) ** Attachment added: 20100703_002.jpg http://launchpadlibrarian.net/51353528/20100703_002.jpg -- [STAGING] r8192se_pci + powertop = kernel panic https://bugs.launchpad.net/bugs/585938 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 585938] Re: [STAGING] r8192se_pci + powertop = kernel panic
(For all the people who found this thread by googling) ### REALLY HACKY SOLUTION WHICH WILL (hopefully) ENABLE YOU TO USE r8192 WITHOUT CRASHING IN LINUX ### The usual disclaimer about these kinds of hacks applies -- I am not responsible yada yada, do this at your own risk yada yada, worked for me, not guaranteed to work for you yada yada. Open a terminal (On Ubuntu 10.04 aka Lucid Lynx: Applications Menu - system tools - terminal) 1) sudo mv /sbin/iwpriv /sbin/iwpriv.old 2) sudo echo '#!/bin/bash' /sbin/iwpriv 3) sudo chmod +x /sbin/iwpriv NOTES: 1) I did this on my machine, and was still able to connect to and use wifi normally. 2) Obviously this will likely break any application which depends on the iwpriv command, and also makes iwpriv unsable for you on the command line (unless you use iwpriv.old) 3) Powertop now runs fine without crashing with wifi enabled and running 4) Other applications may still do the same thing as iwpriv which can cause the crash. This fix does *NOT* address the root cause of the problem. I'm still going to look for a real fix for the underlying problem with the driver. -- [STAGING] r8192se_pci + powertop = kernel panic https://bugs.launchpad.net/bugs/585938 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've also tried the newer version (v17) which still seems to crash. I saw somebody using ndiswrapper somewhere, I havn't tried that yet. Do you think theres any chance of making progress on this guy or should I relegate this netbook to being wireless-less for quiet a while ;( What's funny is that when I first got this machine (~2months ago) it worked fine on wifi. There must have been some update lately which introduced the kernel call that triggers the driver bug (the same thing powertop seems to trigger) or maybe there was an updated kernel introduced which causes bad behavior.
