Exactly the same issue as bug #34722, but for another Vaio laptop: The acpi_sleep=nonvs kernel parameter is required for suspend/resume to work correctly on Sony Vaio VPCEB1S1E laptops. Else, the computer seems to be well suspended, but it reboots instead of resuming. From dmidecode, here's the relevant info: System Information Manufacturer: Sony Corporation Product Name: VPCEB1S1E Thanks in advance!

Created attachment 86611 [details] debug.patch Hi Sébastien: Could you test this new patch on linux-pm next tree? git pull git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git linux-next. There is a new feature of no_nvs_s3 in the pm next tree. Since your problem just takes place in the s3, we should not prevent nvs from being saved both in the s2ram and hibernation. no_nvs_s3 is enough. So please test the new patch again. Thanks.
The new patch works fine too.
Ok. Thanks
A patch referencing this bug report has been merged in Linux v3.8-rc1: commit 876ab79055019e248508cfd0dee7caa3c0c831ed Author: Lan Tianyu <tianyu.lan@intel.com> Date: Wed Nov 21 23:12:12 2012 +0100 ACPI / PM: Add Sony Vaio VPCEB1S1E to nonvs blacklist.
Hi: sorry to bother you again. Could you test your both sony machine's s2ram and s2disk with acpi_sleep=nonvs_s3 kernle param? Thanks.
Sure. Both s2ram and s2disk work fine with acpi_sleep=nonvs_s3.
I see that you have sent a patch for two models of the Sony Vaio, but I have access only to the VPCEB1S1E. Also, to be sure it is OK, I've tested acpi_sleep=nonvs_s3 with the 3.7.2 or 3.7.3 kernel version.
OK. Sorry. I misunderstand. I further consider this test is not safety since these machine already in the blacklist, nonvs always will be set to true regardless param "acpi_sleep=nonvs_s3". So can you test my the new patch? And then I add the "tested-by you" in the patch.

Created attachment 92211 [details] debug.patch Test this one. Thanks.
Hi Len: This bug has already been fixed. The new patch is just to do some optimization since nonvs may not be necessary in s4. I think the bug should be closed. Hi Sébastien: Could you test the new patch?
