I am having a problem getting my Dell Precision 620 with dual PIII 933's and 512 Mb memory to boot 2.6.12-rc3. The problem seems to be the aic7899. The aic7899 driver is compiled into the kernel along with the rest of scsi. I have had to compile in the scsi for every version of 2.6.12-x, but they have all worked until 2.6.12-rc3. I am attaching the output from lspci, the serial console log and the config file. If there is anything else that I can provide, test, etc. I will be glad to do so. -- kr [kr@porky ~]$ /sbin/lspci 00:00.0 Host bridge: Intel Corp. 82840 840 (Carmel) Chipset Host Bridge (Hub A)(rev 02) 00:01.0 PCI bridge: Intel Corp. 82840 840 (Carmel) Chipset AGP Bridge (rev 02) 00:02.0 PCI bridge: Intel Corp. 82840 840 (Carmel) Chipset PCI Bridge (Hub B) (rev 02) 00:1e.0 PCI bridge: Intel Corp. 82801AA PCI Bridge (rev 02) 00:1f.0 ISA bridge: Intel Corp. 82801AA ISA Bridge (LPC) (rev 02) 00:1f.1 IDE interface: Intel Corp. 82801AA IDE (rev 02) 00:1f.2 USB Controller: Intel Corp. 82801AA USB (rev 02) 00:1f.3 SMBus: Intel Corp. 82801AA SMBus (rev 02) 01:00.0 VGA compatible controller: nVidia Corporation NV10GL [Quadro] (rev 10) 02:1f.0 PCI bridge: Intel Corp. 82806AA PCI64 Hub PCI Bridge (rev 03) 03:00.0 PIC: Intel Corp. 82806AA PCI64 Hub Advanced Programmable Interrupt Controller (rev 01) 04:04.0 Multimedia audio controller: Cirrus Logic CS 4614/22/24 [CrystalClear SoundFusion Audio Accelerator] (rev 01) 04:05.0 SCSI storage controller: Adaptec AIC-7899P U160/m (rev 01) 04:05.1 SCSI storage controller: Adaptec AIC-7899P U160/m (rev 01) 04:0a.0 Ethernet controller: Digital Equipment Corporation DECchip 21140 [FasterNet] (rev 20)
