I need some help (again): We have encountered a total freeze while copying files from an SGI/IRIX system (using NFS) onto a local disk on a PC with an Elitegroup K7S6A/SiS745 MoBo, and more than 1Gb RAM, running the LM 8.2 enterprise kernel 2.4.18-6mdkenterprise. This was repeated many times on two different PCs having identical motherboards (K7S6A/SiS745). Then the same experiment was done with the standard LM8.2 2.4.18-6mdk kernel. Now it was not possible to freeze the system. We then compiled the standard kernel in LM 8.2 while including the HIGHMEM option. Now again the PC would freeze while running this kernel. This seems to implicate the use of HIGHMEM. Finally we booted the enterprise kernel from LM 8.1 (2.4.8-26mdkenterprise). Once again it was NOT possible to freeze the system while doing our copy procedure.
These experiments seem to implicate the HIGHMEM + 2.4.18 combination. Note that K7S6A is certified for LM 8.2 by Mandrake. We had to turn off APIC in the BIOS in order to make our NIC work. Would it possibly help to boot the enterprise kernel by the "noapic" option? Or is there really a problem with HIGHMEM in the 2.4.18 kernel? -- Bjarne
