I'm having real problems with current with heavy disk activity. When working in X and updating ports which causes a lot of disk activity I get *very* poor interactive responses. Keypresses can not appear for seconds and mouse movement is very jerky and unresponsive. I'm wondering if something is holding locks a long time in interrupt handlers and causing mouse/keyboard interrupts to be lost? Since this is caused by heavy disk activity then my first guess would be the ATA driver. Is anyone else seeing anything like this? -- Paul Richards <paul@freebsd-services.com> FreeBSD Services Ltd
