=20If I change the harddisks it works fine. If I use 2.5 series kernels it works fine.

sure if driver or hardware) - it is worth trying with the DMA off. That's curious. I have a toshiba portege 4000 with this chipset and yes, dma occasionally conks out on this machine (kernel 2.4.19). It sometimes recovers after disabling dma (automatically, kernel message) and about 20mins of impatience (me) with an ide incomplete command notice Uniform Multi-Platform E-IDE driver Revision: 6.31 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx ALI15X3: IDE controller on PCI bus 00 dev 20 PCI: No IRQ known for interrupt pin A of device 00:04.0.

dma works fine on all other constellations, but I will try it without
dma as soon as 2.4.20 is compiled...
I am running with hdpam -d0 for safety. Peter | ||||||||||
