List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 01 Nov 2006 14:49:24 -0000 Hello, we are experiencing a problem with the speakupmain module (the latest CVS versions with 2.6.18 kernel) on at least one machine here in Brailcom. I can't say much about it except for this: 1) Our target configuration is Speakup with the sftsyn module. We tried to load the modules separately and we are sure the hang happens because of the speakupmain module. 2) The modprobe hangs every time we try to do modprobe speakupmain and when it hangs, the /dev/sftsyn device is still not intialized. 3) After we killall modprobe, the /dev/sftsyn device appears and there comes a notice about it in syslog. The module stays loaded. It is then possible to load speakup_sftsyn and Speakup works just fine. I'm not sure if something is not missing in /proc/speakup or somewhere, but we didn't notice anything strange. 4) Trying to increase modprobe verbosity or kernel logging level reveals no additional information. gdb shows that the hang happens inside the module_init() function in modprobe. Our workaround is (which also illustrates the issue): modprobe speakupmain & sleep 1 killall modprobe sleep 1 modprobe speakup_sftsyn We would appreciate some help with this or some guidance about how could we get more information about it. Also, does someone else experience this issue? Thanks a lot, Hynek Hanke
