[18:06] <alkisg> Hi, we're netbooting over nbd, and a few schools reported that 4.15.0-50 made it very unstable for a few selected clients, so much that they don't finish booting; any related bug reports that I could see if it's what they experience?
[18:06] <alkisg> Temporarily they reverted to the previous kernel and it's working fine again

[19:06] <tomreyn> alkisg: persoanlly, i can't reach alkisg.mysch.gr (194.63.235.156, 2001:648:2302:fc79::22) via grnet-ias-grnet-gw.mx2.ath.gr.geant.net
[19:07] <alkisg> tomreyn: could you try f5? it had some hiccups a few minutes ago
[19:07] <tomreyn> should it respond to pings?
[19:07] <tomreyn> http still times out for me.
[19:08] <alkisg> pings seem blocked currently; it's the greek school network, they play with it frequently; i'll upload to some other site, moment

[19:10] <tomreyn> works. locally, there are no network issues, though, right? since i assume those could cause i/o errors on nbd's, too.
[19:12] <tomreyn> alkisg: ^
[19:14] <alkisg> Reverting to .47 works fine, so I don't suspect cabling,
[19:14] <alkisg> yet the teacher there didn't try a local installation, to see if networking would work there..
