Greetings all --
I recently endeavored to install the same suite of ports on
my sparc64 machines as I have installed on my amd64 hosts.
I installed the smartmontools from /usr/ports (it installed
smartmontools-6.0), configured it thusly:
echo 'DEVICESCAN -a -m somealias@example.com' > \
/usr/local/etc/smartd.conf
And then when I started the daemon:
/usr/local/etc/rc.d/smartd start
Starting smartd.
(pass0:ata2:0:0:0): ATA_IDENTIFY. ACB: ec 00 00 00 00 40 00 00 00 00 01 00
(pass0:ata2:0:0:0): CAM status: ATA Status Error
(pass0:ata2:0:0:0): ATA status: 51 (DRDY SERV ERR), error: 04 (ABRT )
(pass0:ata2:0:0:0): RES: 51 04 00 00 00 00 00 00 00 01 00
And the kernel panic'd:
panic: trap: memory address not aligned (kernel)
cpuid = 0
KDB: stack backtrace:
#0 0xc086c934 at trap+0x554
Uptime: 2h0m44s
Automatic reboot in 15 seconds - press a key on the console to abort
Rebooting...
It's running the GENERIC kernel from 9.1-RELEASE.
lidl@host-2: uname -a
FreeBSD [redacted] 9.1-RELEASE FreeBSD 9.1-RELEASE #0 r243836: Tue Dec 4 15:49:34 UTC 2012 root@heller.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC sparc64
It's completely repeatable. The second time it panic'd, the
machine successfully wrote a crashdump file, and savecore recovered it.
Here's what kgdb had to say:
