Hi list, I'm seeing problems when probing cdrom and floppy devices on a Dell PowerEdge 6850 (4x3.16GHz, 16GB RAM) with CentOS-3.4 using 2.4.21-27.0.4.ELhugemem. When I run snmpwalk the system hangs with 100% wait on all 8 cpu's (in HyperThreading mode) for approx 20s before it goes back to idle state. Same thing if I open/probe any of the cdrom/floppy devices in other ways also. If I BIOS-disable cdrom and floppy and prevents loading of these modules, the symptoms are gone and snmpwalk runs fine. ...but the problem still exits. :-) Has anyone encountered similar problems?
