P'rhaps, thoug I have more thqan one SS5/170 running happily without
major dramas. I've actaully found a repeatable failure mode with the
HME card, though.
ping -f
generates and opps the first time and locks hard if repeated so I
think there's some interaction between the 100Mb interrupt spped and
the CPU/MMU.

I'm guessing that should be 'while' not 'white' :)

Not responding to Stop-A is unusual. But there's an easy way on
the SS5/170 : the TurboSPARC chip is buggy, and there's a code
sequence that lock up the CPU... and gcc _can_ generate
thay code sequence ! It happens on Solaris, anyway...
try compiling:
#
int
main(int argc, char** argv)
{
white(1)
;
}
#
use gcc -O1 (or -O2, can't remember), and lockup your SS5/170... :-(
_maybe_ that's what you are seeing, if it happens only on the 5/170.

Strange, the hme driver has been working fine for me on 2.2.9 an up to 2.2.15-pre9. Then again this is on sparc64, so it is likely related to just sparc32. -- ---===-=-==-=---==-=-- / Ben Collins -- ...on that fantastic voyage... -- Debian GNU/Linux \ ` [EMAIL PROTECTED] -- [EMAIL PROTECTED] -- [EMAIL PROTECTED] ' `---=--===-=-=-=-===-==---=--=---'

SS5/170 hanging with 2.2.14 kernel.
After recently upgrading my kernel version and adding a HME card to my SS5/170, I'm now experiencing random lockup on a very regular basis. I also added support for CS4231 at the same time as I added HME support and am now using fbgetty if that makes any difference. I get no opps, but the machine will not respond to anything including Stop-A. Did anything significant change between .13 & .14 for sparc32? Is there anything I should enable to help provide kernel dumps? I'm now rebuilding a .13 kernel to see if it makes a difference as the machine had been running flawlessly prior to this upgrade. kernel: 2.2.14 compiler: gcc 2.95.2 /proc/cpuinfo: cpu : Fujitsu TurboSparc MB86907 fpu : reserved promlib : Version 3 Revision 2 prom: 2.29 type: sun4m ncpus probed: 1 ncpus active: 1 BogoMips: 169.57 MMU type: Fujitsu TurboSparc invall : 1307 invmm : 1531 invrnge : 2454 invpg : 23272 contexts: 256 -- Stephen "A duck!"
