[09:07:22] <jepler> manipulating /sys power/control entries didn't help thread time
[09:10:49] <skunkworks> heh - just upgraded a 8.04 server. Currently at 12.04 -> 14.04
[09:11:53] <skunkworks> (A project that got shelved for a few years ;) )
[09:13:56] <skunkworks> it was a little dodgy going from 8.04 to 10.04
[09:14:20] <archivist> 8.04 just works!
[09:14:23] <seb_kuzminsky> welcome to this decade! it's 65% over!
[09:34:48] <pcw_home> Did the recent sserial fixes (I think between 2.7.4 and 2.7.5) get merged into master?
[09:56:46] <jepler> pcw_mesa: yes, it should be
[09:58:18] <pcw_home> maybe the forum user has a older version of master
[09:59:13] <jepler> $ git log -3 --oneline origin/master -- src/hal/drivers/mesa-hostmot2/sserial.c
[09:59:16] <jepler> 15aa477 hostmot2: sserial: avoid long wait after lost packet
[09:59:18] <jepler> ad3bf04 hostmot2: sserial: avoid glitches when starting to run
[09:59:21] <jepler> 301005a hostmot2: sserial: actually check if read function added
[09:59:58] <jepler> that was back in may, it would have to be a pretty old tree
[10:00:31] <pcw_home> he's using ja9 (pretty old I guess)
[10:00:40] <jepler> oh yeah I doubt it would be there
[10:01:11] <jepler> the latest sserial update in that branch is
[10:01:12] <jepler> fb177c3 hostmot2: warning when remote sserial device has firmware version lower than r14.
[10:01:38] <pcw_home> yeah thats ancient
[10:01:51] <jepler> .. january 2015
[10:02:33] <pcw_home> yeah, so updating master should fix his issue
[10:10:52] <jepler> yes hopefully. if not, gather more information I guess.
[10:13:11] <skunkworks> ok - I go to busybox when booting 16.04 now
[10:13:34] <skunkworks> how do you dmesg | more? it doesn't work in initamfs
[10:17:43] <jepler> skunkworks: ugh good question. the busybox documentation I found implies dmesg and more are both in busybox, but many parts of busybox can be made optional ..
[10:17:54] <jepler> try: dmesg, and then use shift-pageup to scroll back
[10:18:12] <jepler> try prefixing one or both parts of the pipeline with "busybox": busybox dmesg | busybox more
[10:19:06] <jepler> get a piece of ubuntu 16.04 install media that has a rescue mode, mount and chroot into the installed system, and try doing things like running grub reinstall, kernel reinstall, etc that way ?
[10:30:29] <skunkworks> Thanks!
[10:59:40] <jepler> just shots in the dark, good luck!
[11:09:43] <jepler> it's surprisingly hard to solder blob over an 0805 resistor footprint https://644db4de3505c40a0444-327723bce298e3ff5813fb42baeefbaa.ssl.cf1.rackcdn.com/1ef2cf0240d68c0c669ae7b584a30509.png
[11:10:23] <cradek> I think I have some 0 ohm resistors
[11:10:58] <jepler> s'ok, I did succeed
[11:11:49] <jepler> I was inattentive when ordering parts and got a strip of 820kOhm instead of 82ohm
[11:12:06] <jepler> or 88, whatever it's supposed to be
[11:12:11] <cradek> you'll have to stack quite a few of those
[11:12:19] <jepler> boy I didn't consider that!
[11:13:00] <skunkworks> doesn't that work the same as doubling pennies to get to 1000000? ;)
[11:23:18] <jepler> I should redo this board so the silkscreen "pin 1"s are apparent
[15:06:33] <jepler> zlog: !
[15:07:00] <jepler> skunkworks: hm I missed some of what you said and so did zlog
[15:07:24] <skunkworks> this might just need to be installed.
[15:07:26] <skunkworks> this might just need to be installed.
[15:07:33] <skunkworks> the installed ubuntu doesn't see all the volumes (this install has var and such in separate partitions.) but if you boot from the livecd - it sees all the partitions
[15:08:07] <skunkworks> it is using lvm for some (I think that is the term)
[15:10:33] <jepler> if the root is on lvm, then the initial ramdisk needs to include the kernel module for lvm
[15:11:26] <jepler> possibly the lvm packages themselves containing the userspace parts were removed in an upgrade?
[15:12:41] <jepler> though the package name, lvm2, seems to have been stable from 8.04 through yakkety
[15:46:38] <jepler> skunkworks: maybe some of these pieces of advice, like vgchange, are worth trying? http://dev.overthere.org/wiki/How_to_recover_from_an_initramfs_shell http://askubuntu.com/questions/551446/cant-find-lvm-root-dropped-back-to-initramfs http://askubuntu.com/questions/26886/fixing-unbootable-installation-on-lvm-root-from-desktop-livecd
[15:58:26] <seb_kuzminsky> jepler: thanks for rtapi_open_as_root(), that's handy
[15:59:19] <jepler> seb_kuzminsky: no additional charge
[16:36:37] <skunkworks> jepler, thanks - I will take a look,
[20:34:48] <skunkworks> zlog
[21:31:53] <Roguish> hey, all. is it possible to run machine calibrate from a command line?
[21:32:24] <Roguish> i'm running touchy and would really like to use the calibration/tune thing that is in axis.
[23:29:28] <seb_kuzminsky> getting closer:
