47 Moin Hinnerk,
48 (hopefully have guessed this greet correctly...I am from that
49 part of Germany ;)
50
51 I have the source of the driver exclusivly compiled for 3.8.13
52 as for 3.14.something (cant remember).
53 3.14.x has some other problems (on that embedded platform) like
54 not powering off when shutdown, random reboots and such.
55 So decided to go back to 3.8.13.
56 Yesterday I started updateing (eix-sync and emerge) that Gentoo
57 and it ends up in an endless loop (bash update) of configureing
58 (damn slow on that mini iron) and compiling - as it looks -
59 of a single file.
60 After more than 10 hours I CTRL-C that, reupated and now I am
61 ...updateing the bash again.
62 Sigh.
63 Currently "fun" is something else...
64
65 Is the 3.15.10++ branch free of things like random reboot and
66 not powering off?
67
68 Best regards,
69 mcc
