[fedora-arm] kernel 4.9.2-200.fc25.armv7hl

[fedora-arm] kernel 4.9.2-200.fc25.armv7hl
4.9.2 does not appear to do much good. The blank screen problem https://bugzilla.redhat.com/show_bug.cgi?id=1387733 continues, and the kernel: i2c-bcm2835 3f805000.i2c: i2c transfer timed out message still appears in the journal. The following document my experience: http://ryniker.org/Fedora/arm/dmesg.04 http://ryniker.org/Fedora/arm/journal.04 It is possible there is something odd in my system. (I do not know of such a thing, but there have been enough iterations of "try this... try that" to make it difficult to assert I have exactly what one would obtain from a fresh installation.) As before, blacklisting VC4 allows the display to work. My default target is multi-user, and I can login. I have not tried graphical output. ___ arm mailing list -- arm@lists.fedoraproject.org To unsubscribe send an email to arm-le...@lists.fedoraproject.org
