Yeah. The DMA problems were fixed in the linux-kernel upstream in the next kernel release (which is now quite a few kernel releases back). The endless looping is still an outstanding issue though. I have posted to the alsa upstream about it (see bug #0001246 at "www.alsa-project.org"), but nothing has happened. Perhaps if more people could chip in and say that it fixes problems for them too. If you want to try it, the patch and every kernel I've recompiled (stock debian kernel with the addition of the application of the patch) are avalible at "whitehead.apmaths.uwo.ca/~tyson". The patch is alpha-alsa.patch and the latest kernel flavours I've recompiled are linux-image-2.6.14-2-alpha-generic_2.6.14-4_alpha.deb (my PWS500au uses this) linux-image-2.6.14-2-alpha-smp_2.6.14-4_alpha.deb They should (did on my box) installed fine with "dpkg -i <debfile>". You can also patch up a kernel yourself if you want, but the above images should save you a lot of pain for quick check. Don't forget your have to modprobe the driver with the "isapnp=0" option. As to kernel versions I would not recommend anything earlier than 2.6.14 as that was the earliest release for which all the udev issues were finally sorted out. I haven't tried anything newer as I have not needed to. Let me know how it goes! -Tyson -- Tyson Whitehead (-twhitehe at uwo.ca -- WSC-) Computer Engineer Dept. of Applied Mathematics, Graduate Student- Applied Mathematics University of Western Ontario, GnuPG Key ID# 0xF7666BFF London, Ontario, Canada
