Can you give more details about the issue, the symptoms, possible crash backtrace, way to reproduce it. Without this details, there are very few chances to be able to fix the bug. > 2. rtl8192eu by the driver rtl8xxxu, or the external one 8192eu.ko, does not > connect to any network with that messages into dmesg: > [ 137.936642] wlx000f0064f2d8: authenticate with 00:90:4c:08:00:0d > [ 137.940680] wlx000f0064f2d8: send auth to 00:90:4c:08:00:0d (try 1/3) > [ 138.145146] wlx000f0064f2d8: send auth to 00:90:4c:08:00:0d (try 2/3) > [ 138.353198] wlx000f0064f2d8: send auth to 00:90:4c:08:00:0d (try 3/3) > [ 138.557239] wlx000f0064f2d8: authentication with 00:90:4c:08:00:0d timed > out glibc is not involved at all in the wireless driver, so I don't see the relation with the previous issue. > 3.

There are thousands of packages in different versions between Debian 8 and Debian 9. You have found it's not related to the kernel, but I fail to see how that shows it's a libc6 issue. For example when you have tried the kernel from Debian 9 in Debian 8, have you also tried with the rtl8192 firmware from Debian 9? Anyway if we want to know that the problem is related with glibc, please try to install glibc packages (libc*, possibly locales* and nscd if needed) from Debian 9 onto a working Debian 8 installation and see if the problem appears. Without more information, there is no way for us to fix the bug, so we'll just have to close it. Thanks, Aurelien -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://www.aurel32.net
