Subject: [Regression, 2.6.32->33-rc1] Commit 9f15226e755 breaks resume on Toshiba Portege R500
Date: Wed, 23 Dec 2009 01:58:42 +0100	[thread overview]
Message-ID: <200912230158.42161.rjw@sisk.pl> (raw)

Hi Andreas,

Unfortunately your commit 9f15226e75583547aaf542c6be4bdac1060dd425
(x86, ucode-amd: Ensure ucode update on suspend/resume after CPU off/online
cycle) breaks resume from suspend to RAM on my Toshiba Portege R500 (an attempt
to resume causes a hard hang with 100% CPU load, reproducible 100% of the
time).  This has been found by bisection and confirmed by reverting this commit
on top of 2.6.33-rc1.

Strangely enough, the box doesn't even have an AMD CPU, there's an Intel Core2
Duo in it, so I suspect some missing check somewhere.

If I have the time, I'll look deeper into this tomorrow.

[BTW, I can't recall seeing this patch before.  That very well may be my fault,
but please make sure that CCs of suspend-related patches are sent to me in
future.]

Rafael
