Re: high system cpu load during intense disk i/o

Hello list,

before trying to reproduce the problem with older kernels I did the necessary step of compiling and using a *vanilla* simple monolithic kernel for my measurements. The kernel config (attached config.gz) has many standard things disabled (like ACPI for example) so the oprofile output now seems very different. Please keep in mind that I switched back from libata to the old IDE driver, to be able to use the same config on old kernels.

The situations I attach are:

idle: The PC doing nothing. Note that now idle time is spent in irq_handler and not in poll_idle. Strange... one_disk: Destructive badblocks (badblocks -v -w) on one disk. Everything is responsive and the CPU is 99% iowait as it should. two_disks: Destructive badblocks on two disks before the problem appears. Things are starting to get sluggy. two_disks_bad2: *PROBLEM* The previous situation after several minutes, and after several cron jobs kicked in (and never finished). System in a bad state, highly unresponsive.


The situation seems now completely different (but practically the problem is exactly the same), probably because of kernel options. Here are the first lines from opreport with debugging info, for the two_disks_bad2 scenario:

CPU: PIII, speed 798.02 MHz (estimated)

If you think I should enable/disable other options in the kernel please tell me. Moreover it would be nice to know how to use the various debugging options that I enabled, to help figuring out the problem. So what do you think? Does this help or should I start trying older kernels (which is *hard* to do with latest libc and udev that I have)?


Thanks again,
Dimitris
