Hello!
I am trying to install 9.0-RELEASE from standard amd64 memstick image.
During the install huge amount of "rescan already queued" messages
breaks installer interface.
(noperiph:ata1:0:-1:-1): rescan already queued
(noperiph:ata1:0:-1:-1): rescan already queued
(noperiph:ata1:0:-1:-1): rescan already queued
(noperiph:ata1:0:-1:-1): rescan already queued
So, I have 2 questions:
1) Are these messages harmless?
2) Messages are a little bit annoying. So, is there any way to suppress them?
Some remarks:
1) I am trying to install FreeBSD on HP ProBook 4730s,
which seems to be affected by a recent Intel bug:
http://ixbtlabs.com/articles3/cpu/intel-6x-chipset-bug-p1.html
2) HDD is ada0 on ata0.
3) The messages are genetared constantly:
# dmesg | grep "rescan already queued" | wc -l
98
# uptime
... 14 mins ...
4) I've tried to suppress messages by setting "hint.ata.1.disabled=1",
but this had no effect (may be due to my mistake?)
5) Verbose kernel log has the following part:
