Sure. > Do you have PR numbers? To start with: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=224218 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=223824 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=223803 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204700 Etc., but I should not recite our Bugzilla here. And that hilaroius "75-frames" NFS-related panic requiring tweaks: https://lists.freebsd.org/pipermail/freebsd-stable/2017-July/087477.html There are problems other kinds of problems, that is: - a need to increase kern.cam.boot_delay/kern.cam.scsi_delay (or similar newer tweaks) to make boot happen; - firewall_nat_enable="YES" with GENERIC kernel requires manual loading of modules like alias_ftp.ko or alias_pptp.ko or else NAT would be useless for such transit traffic; - net.isr.maxthreads may be erronously set to 1 by default affecting performance and requiring manual tweak; - zfsloader(8) failing to find any ZFS pool after zfsboot(8) successfully loaded and started zfsload(8) from zpool (PR pending, need to collect more info) - net.graph.maxdata/net.graph.maxalloc do not auto-scale resulting in DoS and lots of other problems within NETGRAPH... I use FreeBSD in many diverse environments and if I strain my memory, I can remember more. (NFS itself is full of surprises...) _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
