I find a problem in Mint and in all versions of Ubuntu since Breezy. It's manifested by stuttering sound and long (30-second) delays in system response. The "fix" is to add "irqpoll" to the kernel boot line, either in the menu.lst file or as an edit during the boot process on a multi-boot system. I know what an IRQ is, so suspect that some piece of hardware is hogging CPU cycles and not letting other hardware devices, e.g. the sound chipset, access the CPU.
But I don't know what "irqpoll" does system-wise, and if it messes up some other aspect of the system's operation. A brief explanation and reassurance would be appreciated.
And is there a way, when booting the live CD, to get access to and edit the kernel boot line? The throbbing sound and long system delays while going through an install can be a real drag.
The mobo is a MachSpeed V4MDMP with VIA KM400 and VIA 8235 chipsets. 756MB of ram. AMD Athlon 2600+ cpu.
Thanks in advance.
