Hi Kernel Gurus,
Please find kindly the description of EIP problems below.
I greatfully appreciate your kind help.
Thank you so much. :)
Much love
Leos.
Brief Description:
=============
1. Today (Dec 4) at 14:43 (GMT+3) EIP was sent, several minutes later my terminal window (on the same machine) got "hanging".
2. Writting text was possible in the window but no prompt came, no reaction on ^C neither ^Z.
3. Mouse: Mouse cursor ok, but it was impossible to switch desktops or windows (in the active desktop) with a mouse-click (no reaction).
4. Otherwise the machine was working (Apache, cron), it also responded to ping from the LAN.
5. I restarted the machine (no fsck required) and since that time it runs ok.
6. Similar problem came yesterday, restart required manual fsck - what helped.
7. Before it was running for 9 months (24/7) when the PC was bought, without any error.
Note: Internet access enabled through FW (yum-updatesd running).
