Re: ravirin down

[James Clarke <jrtc27@jrtc27.com>]

Hi Rod,
Don’t worry; those are all down to me (a kernel module to dump vmap_lazy_nr
and friends, and the DEBUG ones are because I added a printk to see if a
particular condition is reached). Then of course the tst_qtgraphical segfault
is just a normal user-space SIGSEGV.

I’m curious as to whether raverin actually needed rebooting; my monitoring
tool says it was still up 7 minutes ago, but not 2 minutes later at the
next refresh (presumably because you’ve rebooted). Being idle is expected;
there are no packages queued for building.

Thanks,
James
