#667: Kernel Panic at Boot on Intel Mother Boards
-----------------------+----------------------------------

-----------------------+----------------------------------
 When I try to boot either PC-BSD 9.0 stable or 9.1 RC1 after what seems to
 be an uneventful installation on either one of two Intel mother boards,
 the system panics at:
 ZFS file system version 5
 ZFS pool storage version 28
 panic: no usable event timer found!
 cpuid=0
 KDB backtrace:#0  0xffffffff809205 at kdb_backtrace+0x66
 #1  0xffffffff808ed55e at panic+0x1ce
 #2  0xffffffff80c3baec at CPU_init_clocks_bst+0x3bc
 #3  0xffffffff8054bcf7 at mi_startup+0x77
 #4  0xffffffff802b4fec at btext+0x2c
 uptime: 1 sec
 Reboot....

 In both cases, the install DVD loads and runs what seems to be flawlessly.

 The boards in question are:

 Intel D945PSN - Bios:SN94510J.86A.0108.2008.0817.1811
 Intel DP965LT(B) - Bios MQ96510J.86A.1761.2009.0326.0001

 Both systems are 3.0 GHz Pentium D's; one has 2GB and one has 4GB. As a
 test, I successfully installed, booted, and ran FreeBSD 9.0 server and
 Puppy Linux 5.2 on both, so the hardware seems ok. I've tried multiple
 HD's, including a brand new 500GB SATA, and multiple install disks,
 including one distributed by PC-BSD. I updated the BIOS on the older
 board, but to no avail. Power supplies are new 500W units with 3-year
 warranties and different brands. The result was the same for both 9.0
 stable and 9.1 RC1. The 9.0 install disk works well on a newer Socket 775
 ASUS mobo, but I haven't tried 9.1 on that machine.
