I was having disconnects after kernel 2.6.26 with a usb harddrive on an intel mac mini. No USB quirks, or max sector changes helped. in the end I traced the issue to kernel commit b963801164618e25fbdc0cd452ce49c3628b46c8
I reverted the commit (had to be done manually), and everything is rock solid for me on kernel 2.6.32 - 2.6.38
Attached is the patch I am using currently. applies to 2.6.37/2.6.38 (and maybe earlier)
