| |
I've been getting hard hangs with 2.3.{5,15,18,19,20,22} SMP kernels. ("Hard" == screen freezes, no response to keyboard, mouse, ctl-alt-del, or magic sysrq, no more cron logs.)
I do have an IDE disk, but activity on it isn't an issue (contains Windoze for a game (sorry)). My real disk is a Seagate ST34572W on an Adaptec AHA-2940UW (PCI).
The hanging happens repeatably, usually within 20 minutes of starting X, and often immediately after starting X (on console). If I don't start X, there doesn't seem to be a problem. Naturally, I haven't done a heck of lot that way, but I did do some kernel builds with MAKEFLAGS -j3 to get some concurrency, and didn't hang in several hours running.
This has been worse under 2.3.{18,19}; I also got 2 hangs in a couple of weeks running 2.3.15 . 2.3.{20,22} are better; 2.3.20 lasted 1:15 hr:min, 2.3.22 about the same. I tried eliminating a lot from 2.3.18, but it boiled down to SMP being the killer.
I have a 2.3.5 SMP kernel built with egcs-1.1.2-14 (Red Hat), and it seems fine (ran it for many weeks). 2.3.5 built with egcs-1.1.2-18 has hung. I thought this was a smoking gun, but regressing to egcs-1.1.2-14 did *not* fix 2.3.18 . Lately I've been using egcs-1.1.2-24 .
Other hardware info:
Tyan S1682-D motherboard Dual Pentium II, 266 MHz, S-spec SL28L (core stepping C0) 64 megs parity RAM Adaptec AHA-2940UW (is this a common element with other people's hanging?) Seagate ST34572W
SCSI drivers are built-in, not modular.
I have good records of kernel version, .config's, and compiler, so if there are questions, let me know.
