[Bug 1310798] Re: JMicron JMC250 ethernet: networking always disconnected
Alex Cabal, thank you for reporting this and helping make Ubuntu better.
Could you please test the latest upstream kernel available from the very
top line at the top of the page (the release names are irrelevant for
testing, and please do not test the daily folder) following
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional
upstream developers to examine the issue.
If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested exactly shown as:
kernel-fixed-upstream-3.18-rc4
This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.
** Description changed:
- Summary:
- Ubuntu version: 14.04 desktop x64
- Problem hardware: JMicron JMC250 ethernet controller (jme drivers)
- Expected behavior: Ethernet networking works when cable connected.
- Actual behavior: Networking always shows "disconnected", even when cable connected.
-
- Details:
- In Ubuntu 14.04 with a JMicron JMC250 ethernet controller, the ethernet link is always shown as "disconnected", even when the cable is connected and networking is otherwise working.
+ What is expected in 14.04 is ethernet networking works when cable
+ connected. What happens instead is it always shows "disconnected", even
+ when cable connected.
In Ubuntu 12.04, this same ethernet controller also exhibited the same
- problem. However it was fixable by downloading and manually compiling a
+ problem. However it was fixable by downloading and manually compiling a
new version of the jme drivers from here:
- ftp://driver.jmicron.com.tw/Ethernet/Linux/jmebp-1.0.8.5.tar.bz
-
- In 14.04, the above 1.0.8.5 driver no longer compiles and is thus not
- installable.
-
- I tried downloading and compiling the latest source for the driver from
+ ftp://driver.jmicron.com.tw/Ethernet/Linux/jmebp-1.0.8.5.tar.bz . In
+ 14.04, the above 1.0.8.5 driver no longer compiles and is thus not
+ installable. I tried downloading and compiling the latest source for the
+ driver from
https://github.com/torvalds/linux/blob/master/drivers/net/ethernet/jme.c.
This driver does compile, but after installation still doesn't work,
with the wired network status always showing "disconnected".
-
- There is a related Launchpad bug #880316 but that one is for *missing*
- drivers in an older Ubuntu version, not *broken* drivers. (The drivers
- are now included in 14.04, but are totally broken.)
-
- These drivers haven't worked out of the box since 2012... can we get a
- little love here?
