Guest Linux hangs on disk I/O every 30-60 min

Hi, My Virtualbox is the latest 3.2.8, host WinXP 32bit, guest OpenSuse Linux 11.3. Every 30-60 min guest Linux hangs while trying to read/write to/from a disk. Sometimes it's accompamied by 100% use of one of CPU cores, sometimes - not. It seems like guest is infinitely waits for I/O from disk. While hanging, guest OS is responsing to mouse movements and clicks (buttons are raising on mouse move, terminals work) until the needed data are cached in memory. When they need to make disk I/O, they hang too, so finally everything waits for I/O and hangs. Host WinXP works perfectly, only guest freezes. Video mode, network, shared folders - do not affect. I tried 64-bit and 32-bit guest OpenSuse 11.3, it's the same. VDI disks are created in a standard way (expanding file) with limit of 30GB. Inside VDI there is 4Gb /dev/sda1 swap partition and 26gb /dev/sda2 ext4 root fs.
Help me please diagnose/fix the problem.
