hi:
i test hp-tc4100 with red-hat 7.3 today.
it is okay after upgrade to 2.4.18-4.
(2.4.18-3 kernel panic after several hours. just like red-hat said.)
i also test the latest cooker 2.4.18-16
it crashed as usual.
so the problem seems at mandrake kernel.
hope 2.4.19 will fix it.

hi:
our company buy a hp lc2000 server and try to install mdk 8.2 on it.
it can not pass testing and finally we run mdk 8.1 at it.
this time we buy a "certified server" -> hp tc4100.
the machine arrived today and it fail again.
this machine comes with 2 cpu and 1g ram.
to use the memory i must enable highmem(eg: enterprise kernel).
and with highmem enabled we got crash under testing.
i had report this before to:
[EMAIL PROTECTED]
[EMAIL PROTECTED]
and i saw people at list has same problem. but nobody at mandrake
answer these questions.
i also wrote several times to
[EMAIL PROTECTED]
although mdk said that email list is not for supporting, but whom should
i write if the hardware database is wrong??
i'll use paid support tomorrow, but before that, i would like to post it
last time for anyone who is interested..below is my experience with
hp lc2000 last month. and now tc4100 kill me again.

Hello:
i m glad that i got ur reply :) let me describe my problem
and testing procedure in details...i think the problem is
causing by kernel, since redhat 7.2 is fine... and i run
memtest86 to test memories, which are fine..
1.) OSB4 DMA bug. it will cause system hang if u leave the ide dma enabled,
and u try to read a scratched cd which the cdrom can not read well.
redhat 7.2 is fine with dma enabled.
2.) xwindow say mtrr can not use and leave messages below in the syslog:
mtrr: Serverworks LE detected. Write-combining disabled.
redhat 7.2 is fine.
3.) irq conflict in the linux boot message. at bios boot screen i saw
vga using irq 10, lan using irq 9. and cat /proc/pci give me the same
result. but boot message say device 00:04:00(lan) want irq 10, which
already has irq 9.
so i try to lock lan to irq 10 at bios. bios boot screen is fine,
vga using irq9, lan using irq 10, cat /proc/pci give me the same.
but boot message now tell me device 00:04:00 want irq 9, which already
has irq 10... :(
4.) unstable with kernel-enterprise. i test my system with ctcs that
comes with mandrake 8.2. and using ctcs default, so it will run
"kernel making","memory testing" (with memtest86),and "disk testing"
(with badblocks) simultaneously. the system will freeze about 4 hours.
the system didn't hang, just freeze, so no more new process. i can
switch virtual consoles. i login 3 virtual consoles before testing,
one run ctcs,one run top, and one stay at shell prompt.
and when freezing:
the ctcs clock is still ticking at console 1.
the top process is hang at console 2. looking at time at up-left
corner, i can know when the system froze.
i can type command at console 3, the shell prompt, but it will hang
after i hit "enter" if need a new process.
there is a clue but i don't understand. during testing of ctcs,
sometimes there is error below in the syslog:
"kernel: Warning: dev (04:01) tty->count(5) != #fd'(4) in tty-open"
the message appear about every 20-30 minutes. and after about 10
messages, the system froze.
redhat 7.2 with ctcs comes with MDK 8.2 pass the testing for 12
hours...

tbsky
