I use two IDE disks (one ATA100, one ATA33) with UDMA enabled and stock linux-2.4.13. With heavy disk use, I get random corruptions. E.g. "cp -a /usr /mnt; diff -ruq /usr /mnt" shows a couple of files that differ. OTOH, "cp -a linux linux2; diff -ruq linux linux2" use to run fine as many times as you like. Thus I suspect the error is prone to show up on large files transfers over DMA. I talked to Vojtech Pavlik, and we concluded the problem is the transfer between the VIA8233 and the memory (memtest86 show no errors.) I've replaced the motherboard once, without much difference, so it's probably not plain broken. Not using DMA solves the problem, but of course it's not what I want, I get hdparm -t reading around 2 MB/s :-( I'd be happy to try out any solution, I already had to reinstall the system a couple of times due to this. Regards, Micce BTW The sound (ALSA driver) of this board is horrible, but that might be as intended by Soltek;) -- Mikael Hedin, MSc +46 (0)980 79176 Swedish Institute of Space Physics +46 (0)8 344979 (home) Box 812, S-981 28 KIRUNA, Sweden +46 (0)70 5891533 (mobile) [gpg key fingerprint = 387F A8DB DC2A 50E3 FE26 30C4 5793 29D3 C01B 2A22] Nu lubbar vi på fjället hela dan och trivs med det Jesse James '71 militia explosion World Trade Center assassination Mossad $400 million in gold bullion COSCO FSF domestic disruption Monica Lewinsky genetic security jihad terrorist Area 51
