Before pulling from the official git development tree, I tried the
linux-2.6.18-git[n] snapshots. It looks the problem goes back as far
as 2.6.18-git1. Here is a list of test results, for completeness.
2.6.18 ok
2.6.18.1 ok
2.6.18.4 ok
2.6.18.6 ok
2.6.18-git1 fails
2.6.18-git2 fails
2.6.18-git5 fails
2.6.18-git10 fails
2.6.19-rc1 fails
2.6.19 fails
2.6.20-rc1 fails
2.6.20-rc2 fails
Thanks for testing.
Now I guess will pull from the official git development tree and try using
git bisect to narrow the problem further.
Yes, 2.6.18-git1 patch is still near 3MB large, more-over
[EMAIL PROTECTED] adam]$ grep drivers/ide patch-2.6.18-git1
diff --git a/drivers/ide/ppc/pmac.c b/drivers/ide/ppc/pmac.c
--- a/drivers/ide/ppc/pmac.c
+++ b/drivers/ide/ppc/pmac.c
so it looks like some non-IDE commit is affecting IDE driver. :?
