I/O fails with 640MB MO disks due to 2K sector size (128MB MO disks use 512-byte sectors and work fine)
[2.] full description of the problem
There is a problem writing to a 640MB MO disk using FAT or VFAT. The
problem appears to be when reading or writing to a device that has >512K
sectors. The read function can be patched so that using generic_file_read()
routine will solve the read problem. The problem is the write routines. My
machine locks up to the point where I need to reset it. No OOPS information
is available that I can send along (unless there is a way to force a dump).
If someone can *please* help me create a dump (when writing), I can process it, and send you a stack trace. This is something that used to work in 2.2, but now is severely broken. Thanks for your attention...
