Hi there,

When I flash newer BIOS than 1703 (1808 or 1903) laptop suspends to RAM correctly, but resume fails (kernel freezes) leads to total loss of data.

To get BIOS go to:

http://support.asus.com.tw/download/download.aspx

Choose EEE Family -> EEE PC -> EEE PC 901/Linux

1. Why do you think it's a kernel bug?

2. Please try current Linus' tree.

Comment 2 Cijoml Cijomlovic Cijomlov 2009-05-21 06:09:50 UTC

windows still works correctly. At least workaround should exist...

Comment 3 Andrew Morton 2009-05-27 06:45:25 UTC

It may well be a BIOS bug, but we'll be seeing more machines with that BIOS,
so it would be good if Linux weren't to freeze on them.

I'll reassign it to acpi/bios.

please make sure the S3 works again when you downgrade to BIOS 1703.

please attach the acpidump out when using
1.BIOS 1703
2.BIOS 1808

Comment 6 Zhang Rui 2009-06-17 02:47:19 UTC

ping Cijoml...

Hi there,

Asus released BIOS 2001 which fixes resume under linux. So I think this bug can be closed advicing users to upgrade to this one.
