Hello,
as someone already has mentioned for another Laptop, the new Neomagic
Audio-Driver (btw. thank you for creating one) hangs my HP Omnibook 4150
during boot.
The Laptop is equipped with the following Neomagic-Chip:
chip1: <NeoMagic MagicMedia 256AX Audio controller> irq 10 at device 0.1 on pci1
The Stack-Backtrace looks exactly the same as the other mail mentioned. A
little bit further digging into this shows me that on this Laptop every
read access to the second memory-area of the chip in the range of 0x600-0x8ff
brings the machine to a halt. I can read successfully from the areas with
offset 0x0-0x5ff and 0x900-0xFFF. The Header-File states that the mixer-I/O
Area starts at offset 0x600. This access brings the machine to a halt during
boot.
Any suggestions of what I could try?
Michael
