The attached harddisks are newer and allow a higher speed of UDMA100. This combination of older motherboard and newer harddisk causes great problems with 5.X (it never did with 4.X). I have irregular crashes of X and even crashes at initial bootup. All this is solved by using hw.ata.ata_dma="0", which forces the harddisk to use the very low speed of PIO4 :(. Both PCs have a VIA 82C596B UDMA66 controller. I wonder if that is the problem for 5.X ? On these two PCs, the output is of grep -i ata /var/run/dmesg.boot is: -- PC1 ------------------- atapci0: port 0xe000-0xe00f,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 7.1 on pci0 ata0: channel #0 on atapci0 ata1: channel #1 on atapci0 ad0: 43979MB [89355/16/63] at ata0-master PIO4 acd0: CDROM at ata1-master PIO4 -- PC2 ------------------- atapci0: port 0xc000-0xc00f,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 7.1 on pci0 ata0: channel #0 on atapci0 ata1: channel #1 on atapci0 ad0: 76319MB [155061/16/63] at ata0-master PIO4 ad1: 16448MB [33420/16/63] at ata0-slave PIO4 acd0: CDRW at ata1-master UDMA33 ------------------------------------------------- I consider this a serious drawback of 5.3. Any idea how this can be resolved? Best regards, Rob. __________________________________ Do you Yahoo!? Yahoo!
