Hi again, > I also have an 486-DX4-100 PCI ASUS SP3G, and with 2.0.5, reboot from > GENERIC kernel hangs on about every 2nd try.

I have build a that's the same with us! those problems occured with 2.0.5R > custom kernel only yesterday, I dont know yet if that behaves better. > I have cache-write-back and ISA-GAT-enabled, and my SCSI-bus is > triple-terminated (dont ask why ;-) but is quiescent when reboot > hangs, However, as I said, this was no problem with the SNAP > installation. > Well, today we tried several things: we started with the following ChipSet setup: DRAM write page Mode Enabled DRAM code read page Mode Enabled DRAM refresh mode Normal DRAM wait state 0 CPU to DRAM write buffer Enabled CPU to PCI write buffer Enabled PCI to DRAM write buffer Enabled PCI memory burst Disabled Video BIOS cache Disabled Ext. Cache WS 0 Cache update policy Wr-Through PCI posted write buffer Enabled ISA GAT mode Disabled DMA line buffer mode Standard ISA master buffer mode Standard and we tested the machine (partly without the 2nd NCR Controller) until we reached the BIOS defaults (all features disabled, Write Throu, 1 Wait State). The behaviour remained, but now it more occured randomly, about each 3rd or 4th time. Eventually we should test it with an other Kernel where only the really nessesary drivers are configured ?
