18:21 topi`> Ke: get an ATX power, I did that, works very well.
18:21 topi`> just remember to kludge a jumper wire to the "PWR GOOD" signal :)
18:24 Ke> you know mcbin actually has atx connector
18:24 Ke> at some point I have hacked some automotive devices to boot with atx
18:56 topi`> btw do you want an account on my mcbin? :)
18:56 topi`> user account, no root sorry :)
18:57 Ke> hmm, what should I do with that?
18:58 Ke> you mean you are handing out shell accounts for irssi and such, or just for some testing purposes
18:58 topi`> probably nothing :)
18:58 topi`> compile slave?
18:58 Ke> ^^
18:59 topi`> it recently crashed and I have no clue why.
18:59 Ke> mine monero
18:59 Ke> not probably too useful for that
18:59 topi`> so I had to have someone go to the bunker room to do a power reset
18:59 Ke> and that helped?
18:59 topi`> well problem with monero mining is that the algo was designed to require a 2 MB L2 cache to avert asics
18:59 topi`> and the 8040 of mcbin has only 1 MB afaik
19:00 Ke> yeah
19:00 topi`> power resets always help :) but it becomes expensive if I need to send somebody out every week to do a reset
19:00 Ke> if RCS provides I will have power9 in a couple of months
19:00 topi`> I need a lights-out-management
19:00 topi`> oh, the power9 will surely have plenty of L2 :)
19:00 Ke> have you tried watchdog
19:01 topi`> do you mean a hardware watchdog (to cut out the PWR) or some software wd?
19:01 Ke> yeah, Raptor Engineering actually claimed it was cost effective for mining
19:01 Ke> well as hardware as there already is on the board
19:01 topi`> the most effective for mining is a ROCK64 board. I have some, and they manage 14 hash per second and the price is $25
19:01 topi`> hard to beat
19:02 topi`> do you have any docs at hand to enable the HW watchdog on mcbin?
19:02 topi`> is it a feature of the mcbin motherboard, or the 8040?
19:02 Ke> I assume 8040
19:02 Ke> I think linux has a generic driver interface for that, if someone has implemented it
19:03 topi`> dmesg | grep wd gives nothing
19:03 Ke> 1) make sure you have the driver available 2) install watchdog/enable watchdog in systemd
19:03 topi`> maybe this kernel doesn't have it enabled
19:03 topi`> I need suihkulokki's kernel!
19:04 Ke> yeah, suihkulokki's kernel is like a ninja, but cooler
19:05 topi`> my problem is, I loaded up the pre-built kernel I downloaded from somewhere, but forgot to place the modules in /lib/modules
19:05 topi`> lrwxrwxrwx 1 root root 25 Feb 7 2106 Image -> Image-4.4.8-mcbin-marvell
19:05 topi`> that's from my /boot
19:06 topi`> problem is, I can't access UBOOT's console now
19:06 Ke> anyway, I believe there is hw watchdog on the board, as I saw a driver in u-boot that mentioned marvell armada or something
19:06 topi`> until I manage to hook up a box for remotely accessing the UART console of mcbin
19:07 topi`> 536870912 bytes (537 MB, 512 MiB) copied, 0.668543 s, 803 MB/s
19:07 topi`> I have a pretty speedy Sandisk attached to the SATA ports of the mcbin :)
19:08 topi`> hmm, that can't be true, since SATA is limited at around 500MB/s
19:08 Ke> if that was write, did you do fsync?
19:08 topi`> yeah I should have specified fsync on dd's command line
