Summary: Thinkpad T30, new BIOS, and ACPI
Kernel Version: 2.5.70-mm6
Status: NEW
Severity: normal
Owner: akpm@digeo.com
Submitter: peter@peterjohanson.com

Distribution: gentoo
Hardware Environment: T30 with BIOS v2.04 and EC v1.03
Software Environment:
Problem Description: I recently upgraded the BIOS and embedded controller on my
thinkpad T30 to the latest released by IBM. This has fixed the invalid ECDT
table, which had forced me to use the small patch from
http://www.poupinou.org/acpi/ibm_ecdt.html
to get ACPI working. Now the table passes the test, and a lot of the ACPI stuff
works. the problem is now when i close and re-open the lid on my laptop. the
system turns nearly unresponsive, and dmesg shows a *ton* of lines:

ACPI-0295: *** Error: AE_TIME while evaluating method [_L18] for GPE[ 0]
ACPI-0345: *** Error: Handler for [EmbeddedControl] returned AE_TIME
ACPI-1121: *** Error: Method execution failed [\_GPE._L18] (Node c1ae74c0),
AE_TIME
ACPI-0295: *** Error: AE_TIME while evaluating method [_L18] for GPE[ 0]
ACPI-0345: *** Error: Handler for [EmbeddedControl] returned AE_TIME
ACPI-1121: *** Error: Method execution failed [\_GPE._L18] (Node c1ae74c0),
AE_TIME

and top shows events/0 taking about 10% of the CPU. i will attach my dmesg
output from the system before closing the lid.

Steps to reproduce: close lid & reopen it.
