Here's another report of an observed change in EC behaviour since 2.6.24. I don't know if it the warnings are new (i.e. the problem was already there), or if it is caused by regressions due to the changes in EC handling since 2.6.24. Would you like it appended to some bugzilla report? Which? BTW: the problem is not just cosmetic, it is linked with bad data received from the EC (0xFF in two consecutive registers reads, instead of the expected data). Whether it *caused* the bad data to be read, or was caused by something that also caused that bad data to be read, I don't know. ----- Forwarded message from Toralf Förster <toralf.foerster@xxxxxx> ----- At Tuesday 02 September 2008 23:04:06 Henrique de Moraes Holschuh wrote : > On Tue, 02 Sep 2008, Toralf Förster wrote: > > Sep 1 21:25:42 n22 ACPI: EC: missing OBF confirmation, don't expect it > > any longer. > > Sep 1 21:25:42 n22 ACPI: EC: missing write data confirmation, don't > > expect it any longer. > > It shouldn't be doing this. Did you ever get any of those in previous > kernels? From $>zcat /var/log/messages* | grep -e 'Linux version' -e 'EC: missing' | sort it seems to start with straight vanilla kernel 2.6.25.14, happens in *.15 and *.16 too, however the previous kernel 2.6.24-gentoo-r8 didn't log any line of this issue. ----- End forwarded message ----- -- "One disk to rule them all, One disk to find them.
