It is intermitent, but I can force it to occur on every boot if I type on the keyboard while the kernel is loaded (before being decompressed). It happens on a certain machine, with USB keyboard. It does *not* happen with a PS2 keyboard. It does not happen on other machines with USB or PS2 keyboards. I would say this is a hardware problem, as I see it happen only on a certain type of machine. It is custom built by a manufacturer in Spain, with: # lspci 00:00.0 Host bridge: Intel Corp. 82845G/GL [Brookdale-G] Chipset Host Bridge (rev 01) 00:02.0 VGA compatible controller: Intel Corp. 82845G/GL [Brookdale-G] Chipset Integrated Graphics Device (rev 01) 00:1d.0 USB Controller: Intel Corp. 82801DB USB (Hub #1) (rev 01) 00:1d.1 USB Controller: Intel Corp. 82801DB USB (Hub #2) (rev 01) 00:1d.2 USB Controller: Intel Corp. 82801DB USB (Hub #3) (rev 01) 00:1d.7 USB Controller: Intel Corp. 82801DB USB EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corp. 82801BA/CA/DB PCI Bridge (rev 81) 00:1f.0 ISA bridge: Intel Corp. 82801DB ISA Bridge (LPC) (rev 01) 00:1f.1 IDE interface: Intel Corp. 82801DB ICH4 IDE (rev 01) The keyboard is USB. Lilo is 22.4. Problem happens both with 2.4.20-ac2 and 2.4.21-pre5-ac2 kernels are compiled with gcc (GCC) 3.2.3 20030221 (Debian prerelease) and I saw no problems during compilation. All i really need to know is whether it is a Linux problem, a Lilo problem or a hardware problem. Any help I can get will be helpful. I searched the kernel list archives but found nothing similar to this problem. Thank you, -- Pedro Soria Rodríguez psoria@hispafuentes.com
