I'm trying to get a 2.1.6 kernel up and running on a Compaq Prosignia 500. To get 2.1.5 running, there were three changes I had to do: (1) Replace i386/isa/pcibus.c with the version from -current, due to PCI V2 handshaking. This seems to work by default in 2.1.6. (2) Move the lnc0 adapter to be detected like this (in config) >device lnc0 at isa? port 0x7000 net irq 3 drq 0 vector lncintr (3) Add >options "MAXMEM=65536" # 64 MB memory due to Compaq (and Dell) using an extremely irritating aspect of the EISA standard, and saying that they have 16MB in RTC-memory. With this in place, it boots fine under 2.1.5. However, under 2.1.6 it detect the ncr0-device in the Prosignia, print >ncr0: restart (scsi reset) and get a kernel trap (supervisor read from address 0x7 at 0xF0176378) On the 2.1.5, it contnues with the next line >ncr0 waiting for scsi-devices to settle I've tried swapping some of the files back to their 2.1.5 counterparts, but this hasn't helped. I've also tried running with the same pcibus.c as I did under 2.1.5 (from -current late August). If this could be of interest, I'm running GCC 2.7.2.1, which I've compiled myself. I haven't yet tried with a GENERIC kernel, as that won't work on this box anyway (I'll loose my network, and as the box is running as a server...) Anybody got any clues? If not, I'll try to track the bug down further, but I don't want to put down the work if somebody know just what's wrong. -- Eivind Eklund gopher://nic.follonett.no:79/0eivind Work: eivind@dimaga.com http://www.dimaga.com/ Home: perhaps@yes.no http://maybes.yes.no/perhaps/ All of the above is a product of either your or my imagination, and not official.
