(No ctrl-alt-del, no sysrq, only hw reset) [Without that I can boot without problems but I don't have DMA and thus disk throughput is at less than 3 Mb/sec.] The hard lock seems to happen during the first hd access and the hd light stays on when the system is crashing. Is that - a known issue (hopefully not), - a Linux kernel problem or - do I have to blame the board (this is not completely unlikely as I also have problems with two network cards which work without problems in other boards and same kernel) Is the KT266A chipset's DMA supported at all? (The vt82cxx driver source code lists several chipsets including KT266 but not KT266A.) ---------------- Uniform Multi-Platform E-IDE driver Revision: 6.31 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx VP_IDE: IDE controller on PCI bus 00 dev 89 PCI: No IRQ known for interrupt pin A of device 0:11.1.
