I reverted back to the kernel from my previous build that is r268600 and that one still works. The one that didn’t work was r268733. I’m just guessing here but the suspect commit could be: http://svnweb.freebsd.org/base?view=revision&sortby=rev&sortdir=down&revision=268658 Adding the committer delphij to this discussion, can you please comment on this matter? -Kimmo [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Comment: GPGTools - https://gpgtools.org iQEcBAEBCgAGBQJTx18WAAoJEFvLZC0FWRVp5kMH/12PzI5Jafe8ODCn272lZjEW ZuWpjdDIrj8SiM1EbJ8j1wEZx6yPqT76TwaPqwY9NbbShXsK4tNEtkW/MVazd/LH D9L6hUhVy3mVhuKFIEsXkj4tu6y82NpK9JOgSnWbrzyG1ObIHfJg3wvwqMTuCeet jOiX7d6OQsv22yedpQ2Ow50Ardgp9uPTOmueFDJWcVFBeRwJMPmz3j/5QoEiwrvh uC9AR5wwjvZieaQTscONqfebGJdD0yHNqZxNrA2E4vKkZAUxPyIzXou2W7QP0pc7 JGoeYodkSFX9KvBd++TO+IoBSEgC6PjiUwuKKsfc9uv0saYfn3Tc3t+9AQlu9rg= =p08G -----END PGP SIGNATURE-----home | help
