The cause for this could be that the structure queue_head is not being populated. A few attempts that I tried to populate this structure have failed. Can anyone please let me know under what circumstances does this structure get filled up or is there any consistent way to generate a list of pending block requests. Iam aware that this feature is no longer being used in the 2.6 kernels, but was curious to know why this scenario happens on the 2.4 kernels. Regards - Chinmay
