I found a workaround for this, which is to execute "echo 128 > /sys/block/sdb/device/max_sectors" as root". The problem is that that command is needed after every boot, hence I request the Kernel Team to include the fix for the M1 by default. (The exact problem is that the M1 reports higher transfer speed than the one it really suports and It hangs because of that)

@José Luis Ricón, any luck with the ppa?

@Surbhi Palande: Yes! The kernel provided by you solves the issue and I no longer require the workaround, so the applied patch is the correct one. However, I lost privative NVIDIA driver support (not a real problem, since the aim of this kernel was to test the patch).

This small quirk sets the sector size explicitly in the kernel code. This patch is tested by the reporter of the bug. Do consider merging this for Maverick.

Just for good measure, could we get confirmation this patch still fixes the issue in the latest Maverick 2.6.35 based kernel. I've taken the liberty to apply Surbhi's patch in comment #14 to the latest Maverick kernel and build test kernels for both i386 and amd64. Could those affected please test and confirm this still resolves their issue? Thanks in advance.
