Description Maciej Mrozowski gentoo-dev

2008-12-10 08:43:00 UTC

It's a regression in kernel, in USB storage driver, affecting a few models of Nokia phones (in USB data mode, models 3110, 5200, 5300, 5610 6300, 6500 and probably some other). Hard to tell, whether it's actually bug in kernel or in phone firmawe, nevertheless the effect is - that USB data mode doesn't work for those models on kernel >= 2.6.27.

So far I gathered two links (for nokia 6300 and 5300)
http://bugzilla.kernel.org/show_bug.cgi?id=11768
http://linux.derkeiler.com/Mailing-Lists/Kernel/2008-07/msg12252.html

Patch for 6300 solved problem for me:

Who changed summary to "[2.6.27 regression] various Nokia phones report wrong capacity" ?

Does any part of following dmesg log suggest anything about 'report wrong capacity' ?

Comment 3 Daniel Drake (RETIRED) gentoo-dev

I changed it. Yes, your logs indicate that the phone says it has 1 more sector than it actually does. And the patch which you said fixed your problem simply makes the kernel subtract 1 sector from the reported count, further confirming that off-by-one capacity is the cause of this problem.

Fixed in gentoo-sources-2.6.27-r6, thanks for the bug report
