[Rafał 'rmrmg' Roszak]

I have kernel 2.4.21-rc2  (I also tested 2.4.20 2.4.21-pre6, pre7 and
rc1) and when I use 2 channels connect, system crash. Hisax modul is
loaded with parametrs: 
modprobe hisax protocol=2 type=27


System: Slackware 9.0
gcc 3.2.3 (only 2.4.21-rc2 was compiled by this version, rest by
gcc-3.2.2 from slackware package)
isdn4k-utils-3.2p1

Did you enable SysRq with
echo 1 >/proc/sys/kernel/sysrq
If so, can you test if sysrq works while the system is not crashed?

In case SysRq doesn't work only after this crash, can you compile in the
NMI watchdog and boot with parameter
nmi_watchdog=1
That should print a backtrace if your system hangs hard and SysRq does
not work.
NOTE 1: You can see the backtrace only if you are not using X at that time.
NOTE 2: Your system will be dead after the NMI watchdog triggers. Please
write down the backtrace and pass it through ksymoops.

Carl-Daniel

It will be compiled in automatically if you select
"Local APIC Support on Uniprocessors" and "IO-APIC support on
uniprocessors", then boot with
nmi_watchdog=1

If your system hangs for longer than 5 seconds, the NMI watchdog will
print a backtrace on the console.

He'd have more luck with nmi_watchdog=2 on UP (not a lot of UP 
motherboards have IOAPICs)

[root@slack:~#] dmesg | less
