I only saw this message on the console: hde: dma_timer_expiry: dma status == 0x21 hde: DMA timeout error The messages didn't make it to the log on disk. I am using md raid5, so it should have been possible to get the message to disk without hde working. I can't say for sure if the message occured at the same time as the lockup, or sometime before. This was with kernel 2.6.9-1.724_FC3smp. hde is a disk hanging off a PDC20268 PCI card. I'm going to try connecting a PS/2 mouse to see if that makes a difference. JE
