I disabled the relevant ttyd0 entry in the DL145 G2's /etc/ttys and made the other box the server instead of the client (adding the same relevant /etc/ttys entry). The moment I HUP init on the other box, the effect is the same on the G2. The box is hung. Network services such as ssh just halt. ICMP still works tho. And as usual, acpi0 interrupts (and cpu consumption) hit thru the roof: irq9: acpi0 20218233 254 I know that If i disable acpi the serial console works. There's a BIOS update but doesn't really seem relevant as it only fixes HBA stuff: http://h18004.www1.hp.com/support/files/server/us/download/23932.html ( add to that the lousy prerequisite I must have win2k/win2k3 installed ... grrrr) Thanks. > > Sincerely, > D.Marck [DM5020, MCK-RIPE, DM3-RIPN] > ------------------------------------------------------------------------ > *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- marck@rinet.ru *** > ------------------------------------------------------------------------ >
