From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003 Description of problem: Have suffered through trying to get this to work with the aid of RH support personel in RH7.1 and now same problems in 8.0 (Latest Service Request: 227512 contains much information), this has been going on for over a year now before being refered to RH Bugzilla for a fix on this. No audio can be played, attempts to do so causes entire system to lock up forcing a power button reboot to recover. Have gotten it to not crash system at times (unable to determine how to reproduce) which allowed the following to be displayed in dmesg: cmpci: write: chip lockup? dmasz 65536 fragsz 1024 count 65536 hwptr 0 swptr 0 cmpci: dma timed out?? (See attached file cmedia_bug.txt for more details) Of course I can't read this when it does lock solid since CTRL+ALT+Backspace (or DEL) has no response. "Windows XP Pro" and "Knoppix/Linux" has no sound issues when either of these were running on this same system, they both assign the device to IRQ9 though, as you see in the attached notes, RH is placing this device on a shared status @ IRQ5 and is not using IRQ 9 at all. Seem unable to get the device changed over to IRQ9 in RH, no specific BIOS option to force this either. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Run any sound file from system 2.Including "Test Sound" 3.Same in GUI or at shell Actual Results: System Locks up, no sound heard, power off to recover in most cases. Have at some times been able to cancel out of Test Sound without a need to reboot (or force power off). Also at one point did get a very brief, single loud pop noise to come from speakers, then seen same errors in dmesg as reported. Expected Results: Should have heard a Test Sound, any sound, System certainly should not be locking up like this from just trying to play a sound file (any format/extension) Additional info: See attached file for the lspci, lsmod, system details and before and after resaults of running dmesg
Created attachment 90503 [details] lspci. lsmod, dmesg, system info File "cmedia_bug.txt" contains more detailed system and error information on reported bug 85757
This bug exists on my machine with same C-Media chip on a Pentium III running at 1 Ghz with 256 MB/RAM, running Fedora Core 1
