[Bug c/16361] New: kernel built with gcc 3.4.1 don't read my partition on USB

[gregoire dot favre at freesurf dot ch]

I have a 2.6.7-rc2 built with gcc 3.3.? (and all previous kernel) which can
perfectly read my partition table. Then Cooker updated gcc (now 3.4.1) and all
newer kernels didn't read my partition table on usb memory stick...
First I though about the change introduced in 2.6.7-rc3, and then I rebuilt
2.6.7-rc2 with gcc 3.4.1 and I can't read my partition table...
I repported it here : http://lkml.org/lkml/2004/6/12/29

Unfortunately, Mandrake Cooker didn't have gcc 3.3.? anymore...

Any idea what's should be done ? Thank you very much and have a great day :-)

You know you can download, build, and install GCC 3.3.4, you know?
Try that if that does not work, then this is not a GCC bug.
Also try GCC 3.2.3 while you are at it.

What could be the gain of recompiling with an older gcc as I already know it
works with the old release ? I am sorry, I need some more explanation...

Because it sounds like it is a bug in the kernel rather than gcc and you did not provide a testcase so 
there is nothing we can do.

I am sorry to ask for more info, I explained that kernel I compiled with gcc
prior than 3.4.x works perfectly, and that the one with 3.4.0 and 3.4.1 don't
work, then what's the point in compiling again with 3.3.4 as I already know it
works ?

How should I give a testcase for this ?
Just take an Apacer Handy Steno 512Mb memory stick, and try to plug it in a
2.6.6 kernel : compiled with gcc 3.3.4 every thing works perfectly.
With gcc 3.4.1 :
usb 1-2: new high speed USB device using address 3
scsi3 : SCSI emulation for USB Mass Storage devices
Vendor: USB       Model: Flash Drive       Rev: 1.12
Type:   Direct-Access                      ANSI SCSI revision: 02
SCSI device sdg: 1015805 512-byte hdwr sectors (520 MB)
sdg: assuming Write Enabled
sdg: assuming drive cache: write through
sdg: sdg1 sdg2 sdg3 sdg4
Attached scsi removable disk sdg at scsi3, channel 0, id 0, lun 0
Attached scsi generic sg9 at scsi3, channel 0, id 0, lun 0,  type 0
udev[3817]: creating device node '/udev/sg9'
scsi.agent[3741]: disk at /devices/pci0000:00/0000:00:1d.7/usb1/1-2/1-2:1.0/h
ost3/3:0:0:0
creating device node '/udev/sdg2'
creating device node '/udev/sdg4'
udev[3759]: creating device node '/udev/sdg1'
udev[3753]: creating device node '/udev/sdg'
udev[3771]: creating device node '/udev/sdg3'
kernel: FAT: unable to read boot sector

And of course I can't mount it (sdg4).
With 2.6.7-rc2 and gcc 3.3.4 everything is perfect, but compiled with 3.4.1 the
partition isn't read at all by the kernel (as reported under
http://lkml.org/lkml/2004/6/12/29 ).

Please forgive my difficulty in understanding what I should do, I really will do
everything needed as soon as I understand what I should do :-)

With 2.6.8-rc1 and gcc-3.4.1 I cannot read the partition table BUT I can mount
my device with mount -t vfat /udev/sdg /mnt/usb
I have lost the abbility to read the partition table, but I can use it, then I
don't really care about the partition table :-)

Still no valid testcase in 3 months so closing.
