Hi Henrique, I'd like to point you to some things I found out on ThinkPads the last weeks: - IBM T41p shuts down, powersave, Temperature state changed to critical https://bugzilla.novell.com/show_bug.cgi?id=333043 This affects a lot machines (T41(p), T42(p), T43(p), R40) I expect the real culprit is a confused EC (one machine had the problem, the other one not). Anyway, it seems ACPI notifies had higher priority (or did not get scheduled away) in former kernels. Therefore the BIOS could still avoid a critical thermal shutdown through lowering CPU frequency (_PPC) interface on older kernels, but something seem to have changed there... - Latest Lenovo ThinkPads do not like ACPI EC writes for brightness switching (s2ram broken) I've been told it only happens when brightness is set above 7. Don't know, but it seems to be the EC writes > 7 that lets the machine not wake up anymore from a s2ram. - Weird USB - EHCI IRQ problems on very latest Lenovo models Unhandled IRQ messages. Looks like an IRQ (from camera?) gets routed to EHCI pin also? Don't know the details and I am also not very familar with this..., Oliver might be able to point you to bug reports, AFAIK there also exist kernel.org bugs. This is not solved yet, AFAIK. If anyone knows more about this problem, that would be great... Attaching an USB device breaks USB and throws a calltrace https://bugzilla.novell.com/show_bug.cgi?id=325601 As this seem to be a very (recent Lenovo) ThinkPad specific problem -> Only happens on latest ThinkPads, but back to at least kernel 2.6.16 until latest mainline... I hope to get some feedback from Lenovo ThinkPad users also seeing this.
