Are other pm_test values meaningful, or possibly harmful? I think I tried freezer, which resulted in a seemingly perfect suspend, but the machine didn't try to resume afterwards, but booted normally instead... >>> On Wednesday 11 November 2009, Ferenc Wagner wrote: >>> >>>> I already did the test for STR (see >>>> http://bugs.freedesktop.org/show_bug.cgi?id=22126#c3), but will redo >>>> with the current kernel tonight. >>> >>> OK, thanks. >> >> No change on this front, FWIW.

I'm continuing testing s2disk with the platform method under rc7 (with some instrumentation added). Btw, s2ram -f works fine otherwise (no KMS), and my machine is not in the whitelist. I'm not sure whether the KMS problem disqualifies it (shall I report it to suspend-devel?), but it can be identified by: sys_vendor = "IBM" sys_product = "1834S5G" sys_version = "ThinkPad R50e" bios_version = "1WET90WW (2.10 )" -- Thanks, Feri. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
