Via both upgrading from 9.2 to 9.3 and doing a fresh install from scratch, I lost all sound and USB support under SuSE 9.3. I'm stabbing away in the dark and wondering if anyone can offer either quick advice for a fix, a correction to the direction i'm heading now or suggestions for a better approach. Thanks in advance. Apologies in advance if this is much too long. I'm now trying to decipher the SuSE Admin manual, Kernel docs and the RUTE User's tutorial on how to tweak my kernel/modules to get back sound and usb support without breaking anything else. But I'm very uncertain about whether I'm taking the right direction or not. In particular, I've no idea what is meant by the lines under "May 3 10:34:50 tpad01 kernel: irq 10: nobody cared!" I looked at the kernel/module sources, but still don't understand. Below are some potentially relevant errors/warnings in /var/log/messages. In another post, "Sound, USB lost in 9.3" - HAL, D-BUS related?", I provide much more info including the output of "hwinfo --all" (as an attachment). This is all for an old IBM ThinkPad 600x i'm using. SuSE 9.2 worked fine. Knoppix and Kanotix still provide full sound and USB support. Here's the extract from messages -- apologies for length: <cut> May 3 10:34:50 tpad01 kernel: ACPI: PCI Interrupt Link [LNKA] disabled and referenced, BIOS bug.
