I get this every time I boot 2.6.0-test10. I think this problem has been around for a while.
Debug: sleeping function called from invalid context at include/asm/semaphore.h:119 in_atomic():1, irqs_disabled():0 Call Trace: [<c01229d0>] __might_sleep+0xab/0xc9 [<fcff57bd>] ap_cs8427_sendbytes+0x38/0xd2 [snd_ice1712] [<fcfa825a>] snd_i2c_sendbytes+0x22/0x26 [snd_i2c] [<fcfaf15e>] snd_cs8427_reg_read+0x2c/0x8c [snd_cs8427] [<fcfaf414>] snd_cs8427_create+0xa4/0x347 [snd_cs8427] [<c02dc4b0>] snd_device_new+0x20/0x6a [<fcff151a>] snd_ice1712_init_cs8427+0x2f/0x6f [snd_ice1712] [<fcff6153>] snd_ice1712_delta_init+0x230/0x2b9 [snd_ice1712] [<fcff5227>] snd_ice1712_probe+0x323/0x34c [snd_ice1712] [<c017360f>] dput+0x24/0x25f [<c020c833>] pci_device_probe_static+0x4d/0x5e [<c020c87c>] __pci_device_probe+0x38/0x4b [<c020c8bb>] pci_device_probe+0x2c/0x48 [<c0272efd>] bus_match+0x3d/0x65 [<c0273016>] driver_attach+0x59/0x83 [<c02732df>] bus_add_driver+0x9e/0xb1 [<c020ca82>] pci_register_driver+0x6b/0x90 [<fcfa2015>] alsa_card_ice1712_init+0x15/0x4e [snd_ice1712] [<c013cbc5>] sys_init_module+0x14f/0x233 [<c010b3e5>] sysenter_past_esp+0x52/0x71
The system is a P4 with HT, kernel has SMP & preempt enabled. There are two sound cards. Here are all the snd_ drivers mentioned in the output of lsmod:
