[Lubomir Majersky]

Zdravim Vas,

	PC - testovacia skladacka zabehana, MB IntelD915GAG 
(http://www.intel.com/products/motherboard/d915gag/index.htm), CPU Intel 
Celeron 2.53GHz, pamat 2x256MB Kingston, disk IDE Seagate 80GB, dve 
sietovky, jedna z nich je integrovana (82562EZ) na MB a druha 
3C900-combo, bez FDD, bez CD resp. DVD.
	FreeBSD 5.4-RELEASE-p14, ssh, dhcp 3.0.4, mysql 4.1.19, apache 1.3.36 a 
nic viac. Robim na nej len ja, teda ziadne objemy konekcii, dat,

	Myslel som si, ze to bude nieco s mysql, ale nie je to tak. Rebootuje 
to aj bez spusteneho demona mysql.

	Mozno to nie je dolezite a mozno ano, ale doteraz som tu masinu mal 
napojenu takto:

integrovana sietovka (*is*) - lokalna siet
3COM karta - zapojena do internetu

	a pocas "jazdy", prave okolo tej deviatej vecer, som odpojil TP kabel z 
*is* a prepojil som si tu *is* s notebookom a to krizenym kablom, ktory 
je v poriadku. Nedalo mi, tak som to pri restarte dal spat (myslim s 
tymi kablami), a i tak reboot...

	Zacal som nurat v nete, ale nie som o nic mudrejsi

Da niekto tip?
Vdaka
