Could you check the patch below? It makes the code path involving with request_module asynchronous.
With the patch applied all modules were loaded successfully: no hanging modprobe processes anymore.
Thank you for your support.

From: Takashi Iwai tiwai@suse.de Subject: [PATCH] ALSA: seq-oss: Initialize MIDI clients asynchronously
The recent report showed that the initial registration of OSS sequencer clients stuck at loading the sound modules, which involves with request_module() at the init phase. As a workaround, call the registration part asynchronously. (And, this is a better approache irrespective of the hang fix.)
