Bug 267607 – [2.6.28 regression] sys-kernel/gentoo-sources-2.6.28-r5 padlock_sha module hangs on load

• Status: VERIFIED NEEDINFO
• Product: Gentoo Linux

[Description Stuart Shelton 2009-04-26 23:06:36 UTC]

As documented here:

http://bugs.archlinux.org/task/12823

... the padlock_sha module which accelerates SHA operations on VIA processors hangs if loaded on VIA processors(!) - or, at least, the C7.

This is problematic for headless servers which have padlock_sha in /etc/modules.autoload.d/kernel-2.6.  This should probably be checked for and entries removed by the ebuild, or at least a message should be output.

which is the last known working kernel?

[Comment 2 Stuart Shelton 2009-05-12 23:19:54 UTC]

2.6.27-gentoo-r8 definitely worked: I believe that this is a regression in 2.6.28.

According to this commit

http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.29.y.git;a=commit;h=a760a6656e6f00bb0144a42a048cf0266646e22c

this should be fixed on 2.6.29 branch.

Could you please try the latest 2.6.29 sources ? That is 2.6.29-r3

Thanks

Please feel free to reopen after testings as described in comment #3

Apologies for the delay - I've today upgraded to 2.6.29-gentoo-r4, and that works perfectly.
