Latest working kernel version: I *guess* all before 2.6.26 Earliest failing kernel version: Not sure. See above Distribution: Gentoo Linux Hardware Environment: Mobo: Abit IC7-G Software Environment: Problem Description: The problem is about my mobile phone (Sony Ericsson K810i) which normally shows up as two devices (phones internal memory and the memory card in it) when plugging it to USB. Just like any USB Memory stick. The phones internal memory is fine, it shows up as /dev/sdc1 with multi_lun enabled or disabled and it does not show any warnings, thats how the memory card in the phone used to work too. I don't know with what kernel version this started, but let me explain it: When CONFIG_SCSI_MULTI_LUN is set, the memory card does not show up as it should, I only see /dev/sdd but not /dev/sdd1 - it's unable to mount it that way. When CONFIG_SCSI_MULTI_LUN is not set, it does show up as /dev/sdd1 but gives me loads of warnings like "attempt to access beyond end of device", see dmesg for that. This way it is mountable and works fine except the warnings. Steps to reproduce: Plug Sony Ericsson K810i to USB and set it to file transfer mode.

Apparently a regression, too.

This way it is mountable and works fine except the warnings. If /dev/sdd shows up but not /dev/sdd1, then this is probably actually the partition parsing code. There was a change to reject badly formed partitions; I believe someone is trying to revert that change. Matt
