02:21 PM jepler: Uploading "-r9" stretch isos now, ETA about 20 minutes. I haven't tested them, but they incorporate the updated rt kernel from debian.org as well as all security updates
02:23 PM jepler: no changes to the packaging compared to -r9
02:23 PM jepler: -r8
02:23 PM jepler: URL is of course http://www.linuxcnc.org/testing-stretch-rtpreempt/ and using zsync is recommended
02:26 PM skunkworks: jepler, what version?
02:26 PM skunkworks: What kernel I mean?
02:26 PM jepler: Linux rat 4.9.0-4-rt-amd64 #1 SMP PREEMPT RT Debian 4.9.51-1 (2017-09-28) x86_64 GNU/Linux
02:27 PM skunkworks: hmmm
02:27 PM skunkworks: how come when I do an apt-update I don't get .51?
02:28 PM jepler: the debian package name is called linux-image-4.9.0-4-rt-amd64
02:28 PM skunkworks: ah - some packages are held back
02:29 PM jepler: you may need to apt dist-upgrade, because that's a new package (the last one was -3)
02:29 PM skunkworks: right - ok.
02:33 PM skunkworks: find out if this kernel will boot :)
02:40 PM jepler: [and he was never heard from again]
02:45 PM skunkworks: 4.9.0-4-rt-amd64 locks up at login
02:45 PM skunkworks: have to try the live images and see if it is something with my setup
02:48 PM jepler: -r9 are done uploading
02:49 PM jepler: skunkworks: did the earlier stretch iso work on that hardware?
02:50 PM jepler: it's too bad if they've broken something :-/
02:50 PM skunkworks: yes - it just hasn't worked with newer kernels since I installed virtualbox.. but I don't know the exact cause and effect.
02:51 PM jepler: did you install virtualbox via debian or other?
02:54 PM skunkworks: deb http://download.virtualbox.org/virtualbox/debian stretch contrib
02:54 PM skunkworks: from virtualbox
02:59 PM jepler: OK, so any problems would need to be reported to oracle *cough*
03:01 PM skunkworks: heh - yes
03:01 PM skunkworks: I can't download the iso here - internet way too slow - I will test it tonight
03:48 PM seb_kuzm1nsky: jepler: the -r9 iso booted into the installer fine, on my thinkpad T470s
03:48 PM seb_kuzm1nsky: it complained it couldn't find the firmware for the wifi, but then connected to the wifi network ???
03:48 PM seb_kuzm1nsky is now known as seb_kuzminsky
03:48 PM jepler: hi seb_kuzminsky
03:48 PM jepler: thanks for making the most cursory of checks that I couldn't be bothered to do myself
03:52 PM jepler: > It can find Fib(2000) exactly - all 418 digits - in about 50 seconds on an Apple Macintosh PowerBook G3 series 266MHz computer.
03:52 PM jepler: wow boggle at the power of this program
04:02 PM seb_kuzminsky: and after the install it boots and runs fine, though the latency is garbage
04:04 PM seb_kuzminsky: http://highlab.com/~seb/linuxcnc/seb-10Oct2017-96.png
04:09 PM andypugh: Bah! the parport card I found in the back of a drawer is a Moschip and does not do EPP (despite claiming to)
04:12 PM andypugh: (Still working on this 7i43 / 7i90 not-exactly-a-bug thing. Well, back at it after several days distracted)
04:15 PM andypugh: I don’t need it, as I have a working onboard, but it would be nice to test with multiple cards connected.
04:17 PM pcw_mesa: seb_kuzminsky: you might try servo thread only
04:17 PM pcw_mesa: ( If it can't do 25 usec base thread that will mess up the servo thread numbers )
04:20 PM skunkworks: very happy with this laptop. runs hm2_eth really well
04:20 PM skunkworks: latency <30us
04:23 PM skunkworks: http://electronicsam.com/images/KandT/testing/latency1.png
04:23 PM skunkworks: granted - not run very long - but with virtualbox running and all my other crap
05:01 PM skunkworks: I love linuxcnc...
05:01 PM skunkworks: http://electronicsam.com/images/KandT/testing/owordsarecool.png
05:37 PM skunkworks: YaY!
05:59 PM andypugh: Looks like I invented a new card, 7i34.
06:02 PM jepler: well done!
06:02 PM jepler: or, all in a day's work
06:05 PM andypugh: When that commit filters through to 2.8 I will undo the kludge that ensures backwards compatibility for the one guy using 2x7i43 cards and not specifying their ioaddr but instead relying on the defaults.
