Easy Way to FS-corruption

Hi 

I found a way which seems to lead to an "easy" way of fs-corruption:
Install two sound-cards, use the newest ALSA-Drivers 0.5.10b 
(the standard sound drivers don't work to good with sf) and
talk with speak-freely (7.2) with full-duplex enabled and playing
sound on the first card using xmms.
I nearly get a Message to check the fs on the largest partition by hand
on every boot. Any hints or ideas (please, it's so annoying of "loosing" files
every n-th reboot)?
My configuration:
MSI K7T Pro (VIA KT133) with AMD TB 700
Sound Card #1: Leadtek WinFast 4Xsound (cmi-chipset)
Sound Card #2: Onboard Sound Via Southbridge
Graphics: Geforce 256 DDR
Kernel: 2.4.2-pre1 (I didn't manage to get 2.4.2-pre[23] properly patched)
I didn't touch the ide settings with hdparm but the kernel seems to use
DMA by default:
/dev/hda:
 multcount    =  0 (off)
 I/O support  =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 nowerr       =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 3737/255/63, sectors = 60036480, start = 0

Thanks in advance for any hints!
Tim
