I will try building a kernel without legacy IDE drivers, but meanwhile here's the latest bug. Knoppix 6.0.1 is built on kernel 2.6.28.4. Legacy IDE drivers still claim /dev/hda and /dev/hdc (the Knoppix CD being on /dev/hdc). In order to view part of a dump if it occurs, I typed the following boot command: knoppix 3 lang=en keyboard=jp106 When I try to do a TASKFILE WRITE_DMA (LBA28), the process hangs. No dump. Ctrl+C and Ctrl+Z were ignored. Ctrl+Alt+F2 switched to a second VT (by the way this no longer works if Knoppix 6.0.1 is booted to graphical mode). The second VT responded at first. Then tried to do a dd if=/dev/hda bs=512 count=5 | od, and the second VT hanged too. In the third VT, dmesg showed this error message: hda-intel: Invalid position buffer, using LPIB read method instead. Google found several threads where people are blaming this error message on audio drivers or wireless LAN drivers. Some people are saying it was fixed somewhere earlier than 2.6.28.4. 2.6.28.4 tells me it's not fixed, and the timing sure doesn't look like audio or wireless LAN. I'll try building a kernel without legacy IDE drivers, but I wonder which kernel version to try. -------------------------------------- Power up the Internet with Yahoo!
