no way to know ahead of time if it can be done without a lock release. So
code is better off explicitly unlocking the shared/read-mode lock and

ture as an int (hence len=4) in 10ths of a degree K. Then
sysctl(8) is printing this as %.1fC, which is where the 37.0C comes
from. So the sysctl returns an int with some value and then printf

The coretemp sysctl uses the

That limit is completely irrelevant now and should probably be set to

There are two ways to deal with this:
1) edit /etc/malloc.conf and add the 'D' option to force malloc to use

So... any thoughts as to why, after an apparently successful
installation of an xlation, I still get a panic as though there were
no xlation?
Thanks,

Has anyone seen this scenario before? I am seeing it in RELENG_7, but
the code in question exists through to head.
Thread 1:
(kgdb) where
#0 sched_switch (td=0xff003a04ea80, newtd=0xff00210b4000,
flags=Variable "flags" is not available.
) at ../../../kern/sched_ule.c:1944

Yes, that should be it!
After poking around some, it seems ATA/ATAPI-7 Identify
Device word 106 bit 13 is set to 1 and bits 0-3 are set to 3
(for 2^3 or 8 LBAs per sector) for a 4KB sector size (pin 7-8
jumper on a WD AF disks presumably changes this setting to
0,0). See page 121 of Atapi-7 vol
Is there truly no IDENTIFY information to determine the drive format?

The code doesn't use yywrap directly, and this has fixed the build for amd64.
