Hi all, I just put my hands on a shiny HP DC7700, a Core 2 Duo based PC, but I can't boot the installer because it hangs right after detecting keyboard and mouse (PS/2) Does anyone experienced similar issues? googling around I already find some (scary...) info, and tried w/o luck booting with acpi=off (boot, but it seems like hanging on every screen, then eventually go on with the next after some minutes!), noapic and nolapic.
Yes, we have ordered several of these, and Fedora is painfully slow (it runs so much better on a 5 year old laptop). Originally, we thought it might be broken ACPI BIOS implementation and Linux just interacts poorly with it, but we aren't sure. With the v1.06 BIOS update the system will install without disabling ACPI, but it runs about 1/300th the speed it should. One would think with HP's commitment to Linux they wouldn't drop a %#@$!@ like this out on the market. According to a few people in HP's forums, they do not want to hear anything about Linux not running on the DC7700. On FC6 2.16.18-2869: # time ( let X=0; while [ $X -lt 1000 ] ; do let X=$X+1 ; done ) real 0m8.631s user 0m8.385s sys 0m0.203s On FreeBSD 6.2RC2: # time ( let X=0; while [ $X -lt 1000 ] ; do let X=$X+1 ; done ) real 0m0.025s user 0m0.025s sys 0m0.000s I have tried almost every combination of clock= acpi= acpi_os_name="Spoo!" noapictimer nolapic noapic acpi=irq ... that you could imagine with no success in improving the performance. An experimental 2.6.20 (rt) kernel seemed to run about 10 times faster, but it was still to slow to be used. (Screen repaints on login are about 5 seconds) Once, during a reinstall the rescue shell (using x86_64) on the installation CD ran at the same speed as BSD. I have not been able to see reproduce it, ever. I have installed both i386 and x86_64 versions with no real discernible difference in performance. I will assist in anyway I can, if someone wants to help track this down. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
