http://bugzilla.suse.com/show_bug.cgi?id=1075876 http://bugzilla.suse.com/show_bug.cgi?id=1075876#c10 --- Comment #10 from Benjamin Poirier --- The patch from comment 6 will likely prevent the oops but I don't think it's correct for ptp operation to do timecounter_init() with 0. In any case, since the "Failed to restore TIMINCA clock rate delta" message occurs frequently I've extended Takashi's kernel with another patch to log more information about where the failure comes from and possibly try a workaround. Could you install the kernel from project home:benjamin_poirier:branches:home:tiwai:bnc1075876. After a boot when the "Failed to restore TIMINCA clock rate delta" message occurs, please include dmesg. It should have messages like "Failure via adjfreq" and "No SYSCFI in TSYNCRXCTL". https://download.opensuse.org/repositories/home:/benjamin_poirier:/branches:... -- You are receiving this mail because: You are on the CC list for the bug.
