I finally got around to restarting my machine and trying the live CD. First, with the current installation, I took vge0 down to make sure everything was going through vr0. I had the same problem, so I changed the configuration on my openwrt box, put tcpdump on it, and watched. Running csup (which regularly gave me problems), I saw two sets of packets going to the csup server, but never a reply, so each set was just four packets with the usual TCP retry falloff. It worked fine with the live cd on vr0. I rebooted, but kept the CD in. I mounted it, created some ram-backed filesystems on /cdrom/usr/src, /cdrom/tmp, and /cdrom/var/db, chrooted into /cdrom, and did the csup again. It failed, again. I diffed the csups and the libraries csup depends on; only /lib/libthr.so.3 /lib/libc.so.7 differed. They could be bad, or they could have been updated between the live CD being built and me updating. I didn't have any zfs stuff mounted, yet, so it should have been off. Here's loader.conf: padlock_load="YES" vm.kmem_size="1024M" I have seen geli and padlock (Via's on-CPU cryptographic accelerator) have issues where it decrypts wrong. Maybe csup uses FreeBSD crypto, and that takes advantage of padlock (but Samba, too?) Here's how my kernel differs from GENERIC: 79,81d78 < # for zfs < options KVA_PAGES=512 It's worth mentioning that my internet connection isn't quite stable, but I was able to get other machines to csup just fine, so unless my timing was extremely unlucky, there's something up, here. The OS is installed on flash, so I made a few changes. Here's my fstab: # Device Mountpoint FStype Options Dump Pass# /dev/ad0s1a / ufs rw 1 1 /dev/ad0s1f /usr ufs rw 2 2 # var setup /dev/ad0s1e /var ufs rw 2 2 md /var/log mfs rw,-s32M md /var/run mfs rw,-s8M md /var/msgs mfs rw,-s8M md /var/spool/clientmqueue mfs rw,-s16M # tmp md /tmp mfs rw,-s128M I have 2GB of memory, so I didn't bother with swap. I mount /var, but then put things that don't seem to be all that important (and change a lot) in mds so they don't wear the flash too much. None of them seemed *that* important, but I'm listing every weird thing about my system. Memtest said my memory is fine. Ideas?
