I now noticed that the two lines sd *:0:0:0: rpm_resume flags 0x4 sd *:0:0:0: rpm_resume returns 1 are logged once for each sd device (i.e. those with fixed media too) at the startup of hald. Is this expected? Note, I have not seen anything of the sort on another PC which runs 2.3.37-rc6 with the same PM debug options. The differences are that the other PC is an Intel 945GM based one with x86-32 kernel and 32bit Gentoo userland, whereas the PC with log spam is an AMD RS780 based one with x86-64 kernel and 64bit Gentoo userland. Both got hal 0.5.14-r2. -- Stefan Richter -=====-==-=- ==-- =---= http://arcgraph.de/sr/ -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
