Hi all, for some time I have been experiencing weird hangs on one of my servers. When it happens, I can still ping it, but I cannot make any connections or type anything on existing ssh connections. Serial console is also dead, however I can enter the kernel debugger and call cpu_reset() to reboot. Upon reboot all is fine again. Now I discover that my dmsg output contains a few of these: ahc0: PCI error Interrupt at seqaddr = 0x9 ahc0: Data Parity Error Detected during address or write data phase and ahc0: PCI error Interrupt at seqaddr = 0x8 ahc0: Data Parity Error Detected during address or write data phase Thing is - there's nothing connected to the Adaptec. It is enabled, but not used. Can someone in-the-know tell me what exactly these errors mean, and what they might indicate? Ofcourse this MIGHT be the cause of my problems, but I don't know that for sure, and I'd like to know if there are any other plausible explanations for these errors... I will obviously disable the onboard adaptec at the earliest convenience. This is an ASUS P2B-DS board, dual p3 with onboard u2w scsi. Anyone? Thanks, /Eirik
