The machine responds very slugishly while excercizing one interrupt when another interrupt happens. Ex. I'm circling the mouse pointer around the screen, and suddenly the hard drive decides to `sync`, or some such. The pointer then freezes for at least a half-second. It affects the keyboard too. (Though, presumably, it could also be a display issue). I notice myself losing alot of keystrokes as a result of this (I don't know what that means about the problem..) I don't know enough to say that this is about interrupts, but take a look:=20 pryzbyj@andromeda:~$ cat /proc/interrupts=20 CPU0 =20 0: 3835408 XT-PIC timer 1: 9797 XT-PIC i8042 2: 0 XT-PIC cascade 5: 0 XT-PIC Maestro3 7: 1 XT-PIC parport0 8: 4 XT-PIC rtc 9: 1 XT-PIC acpi 11: 310777 XT-PIC yenta, yenta, uhci_hcd, eth0, r128@PCI:1:= 0:0 12: 10454 XT-PIC i8042 14: 11802 XT-PIC ide0 15: 17 XT-PIC ide1 NMI: 0=20 LOC: 0=20 ERR: 0 MIS: 0 I don't recall seeing that r128@PCI:1:0:0 entry there before (I haven't changed hardware, I've been using the console framebuffer for a while, AGP, DRM have always been on). And it seems to be making lots of noise (though I don't know that that's wrong). I do know there's a general problem though - sometimes it feels like I'm using a remote machine when I'm not. It feels to me like it always happens when the disk is accessed (possibly just because I can _hear_ that), and it seems like it happens when the disk hasn't been used in a while. Please Cc: me.
