We should have EDAC drivers that should at least report events,
but so far there is nothing...

I have been downloading many times the same 3.6 GB file from the 
internet with no failures just for testing. I have made a CVS checkout 
of the base system source and pkgsrc source fine.


Also have watched a 1h 30 m film using minidlna server in VLC over the 
local network with no failures at all.


With bwfm driver that was just impossible.

Great work!

Regards.


Hello,

After a week using the driver I can say that it works well downloading 
files massively but I noticed I have lost ssh connection two times (both 
04:00 to 05:00 in the morning when the system was not doing anything but 
sending 15s interval pings) (I left a 15 s interval ping script that 
logged it in a file).Also investigating the logs of my other Zero W with 
Raspbian I could see that at the precise time the network was lost in 
the NetBSD ZeroW, the Raspbian ZeroW recorded an association event to 
the router.


Investigating further I noticed that they could be related to router 
WIFI channel change. "service network restart" a few times luckly 
restores connection but not always works. I tried also ifconfig urtwn0 
up and down manually with no luck. "service wpa_supplicant" restart does 
not work either.


I have systematically reproduced the problem forcing a WIFI channel 
change from the router and network is always lost after that. If you 
return the router to the original channel it returns working sometimes. 
(Raspbian ZeroW always negociate ok channel changes)


Leaving the router at a fixed channel could be a "dirty" fix.

A channel change seems to be not very frequent, so the rebooting script 
when network fails could make sense...I do not know.


A bit tired of testing and out of ideas...


Regards.
Ramiro.

NetBSD and ECC RAM?

[Hauke Fath (SPG)]

Hi,

one my favourite blogs is sporting a page on AMD ECC RAM support

,

linking to

.

Is this of any relevance to NetBSD, or do we just not bother?

Cheerio,
Hauke


(I had a server spit ECC errors recently, and it was kind of nice to 
know...)
