monitor USBdrive access with iotop: no kernel support?

[rych]

Porteus 2.1 LXDE with /porteus/changes

I suspect that my USB flash drive is accessed too frequently, even though I have a 4GB RAM and have put Firefox cache folder on the host system HDD. I'd like to investigate which process is constantly writing/reading the USB. Installing http://guichaz.free.fr/iotop/, didn't work. It's not a bug I guess, but , I'd appreciate advice on how to proceed

Could not run iotop as some of the requirements are not met:
- Linux >= 2.6.20 with
- I/O accounting support (CONFIG_TASKSTATS, CONFIG_TASK_DELAY_ACCT, CONFIG_TASK_IO_ACCOUNTING)

hi rych,

CONFIG_TASKSTATS and CONFIG_TASK_DELAY_ACCT are present already. will enable CONFIG_TASK_IO_ACCOUNTING for 3.0 final.
thanks
