Kernels 2.6.18-2.6.22 work fine, and kernels 2.6.23-2.6.27 lock up after loading the eata module using modprobe, with the error: modprobe exited with preempt_count 1 I've run a git bisection and have a few more passes to go, but suspect the commit in the subject line, [58e2a02eb18393e76a469580fedf7caec190eb5e] [SCSI] eata: convert to use the data buffer accessors to be the patch which triggers the problem. I'm not a C programmer, let alone a kernel programmer, but can build and check any suggested patches. Is anyone successfully using the eata module since the data buffer accessors patch? Is anyone able to examine the code to see if anything was done wrong in the data buffer accessors patch? Regards, Arthur.
