I just tried with a fresh Redhat 7.1 kernel compiled for K6-III arch and got the same problem. I re-ran sndconfig and this time it decided that sound-slot-0 was opl3sa3 not via82cxxx_audio and now sound works. So I dunno why sndconfig produced via82cxxx_audio one time and opl3sa3 another (this is still with the stock RedHat 7.1 kernel, not my compilation of it as I briefly ran). Anyway, I'm resolving this as WORKSFORME since it now no longer fails. |
From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.3llk1 i686) When I attempt to use sound on my machine, it hangs for a long time and prints out messages about via82cxxx timeouts. I've looked at 28334, but it's not that because this bug happens during module loading of via82cxxx driver. Reproducible: Always Steps to Reproduce: 1. Install RedHat Linux 7.1 on an Intel Pentium MMX P150 with laptop install (arch i586). Remove laptop drive and put into I-Opener with AMD K6-III+ processor (arch also i586) Let kudzu do its stuff on boot. No errors seen. The only oddity here that is different from a normal install is moving from an Intel to and AMD version of an i586 arch. However, this is how I installed 6.2 and 7.0 and sound worked in them. (I am presently recompling the kernel supplied with RedHat 7.1, with the K6 flag set, to make sure it is not that.) This is a fresh install, not an upgrade. No /etc/isapnp.conf file is present. 2. Attempt to use sound (sndconfig, or just do startx with gnome as default) Same errors can be achieved by doing "modprobe via82cxxx_audio" directly instead of running a program that uses sound. Actual Results: Get timeout errors on via82cxxx. Eventually command (sndconfig, startx, whatever uses the sound chip) exits. Expected Results: Sound should have worked, as it did with RedHat 7.0.
