Description Bill Nottingham 2004-01-29 15:49:47 EST

The installer transfers the install image, and (apparently) does the
changeloop ioctl. The installer then becomes stuck in disk wait, in
the loopback code.

syslog with sysrq dumps attached.

reason: bio_alloc(..., 0) leaves a lot of stuff uninitialized.  Fix:
use bio_alloc(GFP_KERNEL, 1); and explicitly set bio->bi_bdev to NULL
in the loop_switch().  After that it works here(tm).

Fix integrated into 2.6.1-1.65.
