I thought Linux *was* a kitchen sink until I saw some of the ideas here for 2.1 ;)
Anywho:
I took the plunge and booted my systems under 2.0, but it's turned out poorly. My system is a redhat-3.0.3 based system with the usual updates to handle 2.0*.
It's crashed several times since Sunday. The first time it continued to limp along saying:
Jun 11 19:46:00 pace kernel: Problem: block on freelist at 0043b40c isn't free.
every minute. Poor bash couldn't fork to exec anything for lack of memory, and it was just a big mess.
The second two times it's died much worse, spewing data to the console and being totally unusable. The data it spews looks like a dump of some sort: [xx xx xx xx xx] [xx xx xx xx xx], ad nauseum.
My other machine died last night as well, but its console was screen-saving and wouldn't go on, so I couldn't see whatever it said.
Did anyone ever put in kernel crash dumps of some sort so I can figure this out? Without even a regular panic message, I'm unable to find why it's dead. It seems to crash more frequently when traffic to the w95 box picks up, but that's mostly just a feeling, and the non-routing machine also crashes.
The following things are happening on my systems and network. Do any of these things tickle known bugs in 2.0?
- 1 unpatched Win95 box on the network routed and samba'd by Linux. - 1 ne2000 clone, driver not a module, in each. - Both the plain ISA system and the VL/ISA one crash. - 16M or 8M with the 16M limit specified - Kernel compiled for 486. Crashes on both Intel and AMD 486s. - Both linux systems mount nfs from each other, nfs is a module. - kerneld, etc from modules-1.3.69k
The following things are interesting but probably not it since they happen on only one of the two crash-prone systems (albeit the more crash-prone of the two):
- PPP connection (to a Cisco of unknown rev) via modem on an STB 4COM. - 1 each of disk, CD, and tape on an aha1542. non-scsi box dies too. - IP accounting and firewalling; ~5-15 rules per chain.
Needless to day, neither system crashes under 1.2.13 w/ELF and whatever other patches redhat put in.
* "The usual updates to rh-3.0.03 for 2.0" is defined as:
SysVinit-2.62-1.i386.rpm ipfwadm-2.1-1.i386.rpm modules-1.3.69k-1.i386.rpm ppp-2.2.0f-1.i386.rpm procps-0.99a-3.i386.rpm
