Our company has recently purchased two Acer 5632WSMi laptops and we're running Gentoo x86 unstable on them. The most hindering problem that's currently plaguing us is the IDE chipset. Without the combined_mode=libata on the command line, DMA is disabled and the hard drive just uses PIO. With libata, it hangs up randomly, causing the driver to eventually clock down to PIO mode too. I'd be willing to test patches (like really INSANE ones), because the laptop's not too critical currently. I can post the full dmesg and lspci -vvnn if it might be of use. I have no idea whether this problem has been solved or reported before.
