Steps to reproduce:
boot the computer, modprobe mv_sata, and then rmmod mv_sata.
Comment 1 Diego Calleja 2006-07-30 11:29:22 UTC
Does it still reproduces in recent kernels? (libata is moving target)

If so, can you try 2.6.18-rc3? There's a better error handlind there and may
oputput more useful info.
Comment 2 Adrian Bunk 2006-10-05 14:40:04 UTC
Please reopen this bug if it's still present in kernel 2.6.18.
