Hi everyone!

I recently installed 5.0-CURRENT-20021215-JPSNAP from 
current.freebsd.org and two small problems have come to light.

Firstly my box (a P2-350 Compaq Deskpro) refuses to reboot. When I issue 
a 'shutdown -r now' the system gets as far as displaying the system 
uptime and then seems to stop. The monitor goes into powersaving but the 
machine never reboots, and I need to hit the power button to get it to 
reboot. I tried disabling ACPI by adding hint.acpi.0.disabled="1" to 
/boot/device.hints but it made no difference.

Secondly when I first installed -current onto this machine (DP1 I think) 
I had a strange problem where the system's dmesg becomes corrupted. This 
problem is still present and seems to be able to appear and dssappear. 
Here is an exerpt from dmesg where the corruption suddenly appeared :

uhci0: <Intel 82371AB/EB (PIIX4) USB controller> port 0x2020-0x203f irq 
11 at device 20.2 on pci0
usb0: <Intel 82371AB/EB (PIIX4) USB controller> on uhci0
usb0: USB revision 1.0
uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered
pci0: <bridge, PCI-unknown> at device 20.3 (no driver attached)
orm0: <Option ROMs> at ikmem 0xe0000-0xe7fff,0xc0000-0xc7fff on isa0
pmtimer0 on isa0
atkbdc0:<Keyboard controller (i8042)> !t port 0x64,0x60 onisa\^P
atkbd08 <AT Keyboard> blags0x1 irq 1 on adjbdc0
kbd0 at atkbd0
fdc0: <Enhanced floppy conTroller (I82077, FE72065 or alone     > `t 
port 0x3f7,0x2f0-0x3f4 )rq 6 drq 2 on isa0
fdb0: FIFO enabled, 8 b\^Xtes thR%shmld
fd0: <144\^P-K@ 3.%" dpive> on fdc0 drive\^P

Both of these problems have been reported to -current before but never 
with any resolution. As we near 5.0-REL, I thought I would check again 
if anyone has any ideas on what might be wrong.

Many thanks.
