Hello all, in short: while having heavy network accesses (>50 ftp connections) my system from time to time hangs (no inputs are noticed anymore) ore crashes (a few times it reboots itself safely). Sometimes I found Oopses in my kernel log. Some Oopses are "NULL pointer dereference" in try_ro_read_ahead (25 times), generic_file_read (12 times), update_vm_cache (4 times) and ret_from_sys_call (1 time). Others are "Unable to handle kernel paging request" in get_write_access (1 time). Around are some "general protection: 0000". I'll include a sample of all the listed Oopses but could also post the whole log file (170K) if it would be helpful. This Oopses happened some hours (1.5 - 15) after booting and the reboots between 5min and 5h after the last error was recorded. Now I reduced the network access and the system seems to be more stable. My system configurations: - cpu: cyrix 6x86 P166+ - chip set: intel 82430 FX (with "Intel 82371 PIIX (Triton I/II) DMA support" enabled the transfer rate of the first channel grows from 6Mb/s to 11Mb/s but the second reports an interrupt problem: "irq timeout: status=0x58 { DriveReady SeekComplete DataRequest }" and disabled DMA) - ram: (tested with memtest-86 but nothing found) - network card: realtec ne2000 pci clone (with 3com 905b-tx it happens more often but without off any messages) - disk: two EIDE (IBM DHEA 6.4GB and IBM DCAA 4.3GB) - cdrom: mitsumi FX120T - zip-drive on ISA aha152x (never used within kernel release 2.0.35) - soundcard: sound blaster 32 AWE (awe driver not included)
- Kernel: ($ cat /proc/version) Linux version 2.0.35 (root@Nummer1.saw.rwth-aachen.de) (gcc version 2.7.2.3) #23 Mon Sep 28 12:30:54 CEST 1998 - ip-firewalling and masquerading - soundcard as module - memstat module from xosview (for a correct display of shared memory)

Thanks for your interest Jan Menzel
PS: Please let my know if a cane do anything to fix this problems as quick as possible (its impossible to use this system as server anymore). Thanks again.
