I recently loaded Fedora Core 1 on an Intel Box. It's a pretty standard box. I am running behind a proxy that required authorization, but I got that part working fine. I can do an up2date -l with no problems. However, when I do an up2date -u (or use the GUI), it runs through the procedures, but when it starts calculating the rpm dependencies, the machine hard locks. You can't ping it, Control-Alt-Delete, no mouse movement, no response to keyboard, it's locked hard. I would also like to mention that I was running BSD/OS on this box before with no problems for months, so I think it's unlikely that it's a hardware problem. Since Linux has more advanced networking capabilities, I would prefer to run Fedora. What do I do to figure out what's causing the hard lock? Any advice or suggestions greatly appreciated! Thanks, <> Jim I am attaching some info on the box in case it's helpful: fedora{root}:/root<95>uname -a Linux fedora.localdomain 2.4.22-1.2115.nptl #1 Wed Oct 29 15:42:51 EST 2003 i686 i686 i386 GNU/Linux fedora{root}:/root<96>lsmod Module Size Used by Not tainted soundcore 6468 0 (autoclean) ide-cd 35776 0 (autoclean) cdrom 33728 0 (autoclean) [ide-cd] bridge 25172 2 (autoclean) parport_pc 19076 1 (autoclean) lp 9060 0 (autoclean) parport 37056 1 (autoclean) [parport_pc lp] autofs 13364 0 (autoclean) (unused) e100 56100 5 floppy 58012 0 (autoclean) sg 36492 0 (autoclean) (unused) scsi_mod 108168 1 (autoclean) [sg] microcode 4700 0 (autoclean) keybdev 2976 0 (unused) mousedev 5556 1 hid 24708 0 (unused) input 5888 0 [keybdev mousedev hid] usb-uhci 26380 0 (unused) usbcore 79168 1 [hid usb-uhci] ext3 71300 2 jbd 52084 2 [ext3] fedora{root}:/root<97>dmesg Linux version 2.4.22-1.2115.nptl (bhcompile@xxxxxxxxxxxxxxxxxxxxx) (gcc version 3.2.3 20030422 (Red Hat Linux 3.2.3-6)) #1 Wed Oct 29 15:42:51 EST 2003 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000003fffc000 (usable) BIOS-e820: 000000003fffc000 - 000000003ffff000 (ACPI data) BIOS-e820: 000000003ffff000 - 0000000040000000 (ACPI NVS) BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved) 127MB HIGHMEM available. 896MB LOWMEM available.

Additional comments: There is no cdrom in the drive. I also tried disabling bridging and just using one active NIC (all others set to down) to see if it's something with bridging. No difference, still hard locks. Also seems to hardlock with some screensavers although this I've seen before. I think some 3D screen savers cause problems with certain video cards/drivers.
