Hey ho. I am still bumfuzzled regarding my recurrent errors with my intel8x0 card in my NEC Versa P520 laptop. As far as I know, others with the same laptop are not experiencing these semaphore errors.
The problem is that I often lose the soundcard completely, and see these messages in /var/log/syslog. Mar 2 10:32:41 euclid kernel: ALSA sound/pci/intel8x0.c:591: codec_write 0: semaphore is not ready for register 0x2c Mar 2 10:32:41 euclid kernel: ALSA sound/pci/intel8x0.c:607: codec_read 0: semaphore is not ready for register 0x2c I cannot predict when the semaphore error will raise its ugly head. It appears to be unrelated to ACPI, since I have no support for ACPI in my 2.6.3 kernel. Today, I noticed that my soundcard shares an IRQ with my SMBus (whatever that is). After the semaphore error above, I ran "alsasound stop" to unload the modules and tried "alsasound start" to load them. As expected, the load failed. I noticed the following in dmesg. PCI: Found IRQ 5 for device 0000:00:1f.5 PCI: Sharing IRQ 5 with 0000:00:1f.3 PCI: Sharing IRQ 5 with 0000:02:07.1 PCI: Setting latency timer of device 0000:00:1f.5 to 64 ALSA sound/pci/intel8x0.c:1987: codec_ready: codec is not ready [0x700001] Intel ICH: probe of 0000:00:1f.5 failed with error -5 I looked up that device and found the following. 00:1f.3 SMBus: Intel Corp. 82801DB SMBus (rev 03) Is this relevant perhaps? I'm clutching at straws here. I'd really like to find the solution to this persistent problem (which began in November). -- "Customers have come to SCO asking what they can do to respect and help protect the rights of the SCO intellectual property in Linux.
