Subject: x86_64 panic on latest linux-2.6

Hello,

	My x86_64 box is not willing to boot.

http://tuxland.pl/tmp/s7300372.jpg (275kB)

(gdb) p blk_lookup_devt
$1 = {dev_t (const char *, int)} 0xffffffff8032a430 <blk_lookup_devt>
(gdb) l *(0xffffffff8032a430+0x7f)
0xffffffff8032a4af is in blk_lookup_devt (block/genhd.c:664).
659             dev_t devt = MKDEV(0, 0);
660     
661             mutex_lock(&block_class_lock);
662             list_for_each_entry(dev, &block_class.devices, node) {
663                     if (strcmp(dev->bus_id, name) == 0) {
664                             struct gendisk *disk = dev_to_disk(dev);
665     
666                             if (part < disk->minors)
667                                     devt = MKDEV(MAJOR(dev->devt),
668                                                  MINOR(dev->devt) + part);
(gdb)
