I tried that, but didn't seem to help much.
I run 'make -j4 buildworld' twice, just in case, and got the same
warning the first round, but didn't on the second.
One thing I noticed is that, the first warning occurs on a idle disk,
not the one running 'buildworld'!
FYI, my system configuration:
ata0 -- master: ad0s1 (Win95), ad0s2* (-STABLE) slave: none
ata1 -- master: ad2s1 (DOS), ad2s2* (-CURRENT) slave: none
I was running 'buidworld' on -CURRENT (ad2s2), at that time -STABLE
and Win95 partitions where mounted, but basically idle.
IIRC, buildworld was working on lib/libc when the warning occurred.
So, it may be that, system was too busy talking to that running disk
with loads of small-file transfers, and timed its-self out on the other?
Thank you,
Haro
