Hi, I have a kernel from Mon Jul 19 01:06:15 CEST 2004 and it's terribly slow, especially while executing applications in parallel. Following symptoms: - mouse cursor is non-responsive for 3-5 seconds - hard-disk is slow and is unusually active (portupgrade needs about 15 minutes till it arrives compiling first port) - printing is slowed down a single line needs about 10 seconds - syncer is slowly counting vnodes down and needs a few seconds till it arrives at 0 I have also discovered this, after starting the print job: Jul 23 19:35:32 Interrupt storm detected on "irq7: lpt0"; throttling interrupt source Remarks about my -CURRENT kernel: I have played with some kernel settings earlier: - SCHED_4BSD, because UPDATING said so - DEVICE_POLLING is now off in this kernel I'm just reporting it, because it might be related with the instability issues, which you mention here. Any ideas what I should do now? Martin
