they where all created by my user(uid 1000)
Could somme exectable be crafted to have set uid bit and 
owner of uid 0?

i was also building a cvs checkout of wine. the first
build was successfull, then i make clean and make again.
it stop on that error:
async.c:75:19: warning: netdb.h: Value too large for defined data type
async.c:83:21: warning: resolv.h: No such device

i've never see somme thing like that before.

additionaly logs report:
hdb: dma_timer_expiry: dma status == 0x60
hdb: DMA timeout retry
hdb: timeout waiting for DMA
hdb: status error: status=0x58 { DriveReady SeekComplete DataRequest }

hdb: drive not ready for command
init_special_inode: bogus i_mode (173005)
Cyclades driver 2.3.2.20 2004/02/25 18:14:16

Whit the DMA timer expire, i look like a hardware probleme
but i've been runing other distribution before on this
system and i never got surch error.

closing as the kernel don't set the setuid bit on files 
also the dma failure looks much more then dying hardware.
no furture report since initial post.
