Dell Inspiron 640M
Intel Core2Duo (t5600)
vga intel gma950
ram is tested with memtest and is ok.
I've got the same prob;em but on fedora 8 64bit.
i've detailed my problem in here
In summary i can SOMETIMES boot without acpi=off || irqpoll, sometimes the NIC
doesn't work. I am pretty sure that my NIC isn't busted either becaused if i
boot into vista straight after to check it automatically logs onto the net.
My exact hardware specs are;
Samsung SpinPoint T 500GB SATA-II 16MB Cache - OEM (HD501LJ
Samsung SpinPoint T 320GB SATA-II 16MB Cache - OEM (HD321KJ)
Corsair HX 520W ATX2.2 Modular SLI Compliant PSU (CMPSU-520HXUK)
Corsair 4GB DDR2 XMS2 PC2-6400C5 TwinX (2x2GB)
Intel Core 2 Quad Pro Q6600 "Energy Efficient SLACR 95W Edition" 2.40GHz

EVGA GeForce 8800 GTS "Crysis Edition" 512MB GDDR3 HDTV/Dual DVI (PCI-Express) -
Thermalright Ultra-120 Extreme CPU Cooler (Socket AM2/LGA775)
Samsung SH-S203NRSMN 20x DVD±RW SATA Dual Layer Lightscribe ReWriter

Abit IP35 (Socket 775) PCI-Express DDR2 Motherboard
Antec Solo Quiet Mini Tower Case - No PSU
Dell 22 inch Widescreen Flat Panel Display with built-in Webcam (SP2208WFP)
Auzentech X-Plosion DTS Connect 7.1 Sound Card – Retail
Just for reference, the same thing happens in ubuntu but if i boot with acpi=off
and irqpoll the sound card is always detected unlike fedora where it's detected
only somtimes. I hope this gets fixed before fedora 9.
Kernel no; 18.104.22.168-137.fc8. I done a full system update about a day ago.
thanks for your time.
Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:
Is this bug still present in Fedora 8 or Fedora 9 with latest kernel upgrades?
Works well on latest f8 and f9 kernel.
I can't test on f7 anymore.
