Previously I had reported that recent revisions were causing my computer to
freeze when using kernel 2.6.15-gitX. In fact, it freezes under kernel 2.6.14
as well. By using the svn 'export' command, I was able to locate the patch that
causes the problem, which was part of rev 661 and listed below. From an added
printk statement, I know that the branch that skips just the PLCP header is the
one taken. The freeze happens a little bit later - thus the actual cause is not
yet known. I am continuing to try to find the problem; however, if anyone has
any suggestions, I would appreciate any help I can get. Once the problem
happens, I have to turn the power off to get the machine restarted.
Fortunately, I use a Reiser file system and do not have to endure a lengthy
fsck. Thanks, Larry
