DL160g5p strange problem with the system console

[Vyacheslav Druzhinin]

Hi,

I've tried to install various releases 7.0, 7.1, 7-STABLE and 8-HEAD on the 8-core server (dual Xeon) with the same effect. I can't get what is going on with the system console. Changing to the second console by pressing Alt+F2 takes lag about two or three seconds  on 100 idle system.  If I starting to press Alt+F1 and Alt+F2 rapidly, as fast as I can, the load of the system grows up incredibly.

# top -SH

last pid:   945;  load averages:  1.95,  0.55,  0.20                                            up 0+00:52:22  09:33:44

23 root     -24    -     0K    16K WAIT   3   1:57 100.00% swi6: Giant taskq
19 root     -32    -     0K    16K WAIT   2   1:55 100.00% swi4: clock sio
34 root     -64    -     0K    16K WAIT   1   1:55 100.00% irq23: uhci0 ehci0
   
What does it mean? Why switching betwen system consoles take lag? Why it loads a system?
Also I've tried to compile kernel without it:

device          uhci            # UHCI PCI->USB interface
device          ohci            # OHCI PCI->USB interface
device          ehci            # EHCI PCI->USB interface (USB 2.0)

but the PS/2 keyboard become unworked. Why the usb subsystem interacts with the PS/2 keyboard?

And after that I've tried Fedora 9, it runs without any lags in system console.

Please, can anybody help me with this lags? I thought if it lags something going wrong with the system.

Any help would be appreciated.

WBR,
Vyacheslav.

Hi,

I didn't pay attension on these messages in dmesg. I think it must be important

Jan 19 15:07:31 newmail kernel: atkbdc0: <Keyboard controller (i8042)> at port 0x60,0x64 on isa0

I googled the same errors occur on  IBM e345 server, the hint was to use usb keyboard. I haven't one. I'll try to search for a usb keyboard later.

One more thing... all the distros I tried before was AMD64, right now I'm booting from i386 RELEASE 7.0 ... and it's just works!! What a mess!!

ukbd0: <ServerEngines SE USB Device, class0/0, rev 1.10/0.01, addr 2> on uhub0 kbd0 at ukbd0
ums0: <ServerEngines SE USB Device, class0/0, rev 1.10/0.01, addr 2> on uhub0

It's awful but I can't use i386, I lose 4Gb of RAM of the total amount of 8Gb RAM. :(
Is it possible to fix AMD64 drivers for that usb devices?

WBR,
Vyacheslav.
