Description Bill Nottingham 2004-01-29 15:49:47 EST
2.6.1-1.63.

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.
