[This sortof follows the format of the report form in REPORTING-BUGS]
1. I've found a consistent set of circumstances which will hang 2.4.x kernels
on my system.
2. If the system is put under load to the point where it swaps heavily
(swapping appears to be pre-requisite, based on a little messing about), and
then given commands to use the floppy drive (mount, ls -- anything which
necessitates reading/writing to the floppy), it will hang with no message (it
does not OOPS, or at least it can not to the root console) I've done this
several times, with different disks and kernels, with and without X.
3. Hang, floppy, vm, swap
4. 2.4.0, 2.4.1, compiled on egcs gcc 2.91.66
7. My system is a K6 (well behaved to date, w/o bug, afaik) on an Acer mb;
ALi M5229 IDE, ALi M15nn bridges... Unfortunately, I can't give the precise
mb at the moment...
However, if necessary, I can find out (system was bought as an IBM desktop,
therefore the documentation is totally useless and in order to find anything
out about hardware I either have to cunningly read the boot logs/ISA probing
& interpret or read the green-on-green writing on the mb)... I can't think of
any other relevant details, but I would be happy to respond to additional
queries for information.
7.2 Relevant /proc/cpuinfo :
processor : 0
vendor_id : AuthenticAMD
cpu family : 5
model : 6
model name : AMD-K6tm w/ multimedia extensions
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr mce cx8 mmx
[the rest of the bug reporting form seems excessive...]
I hope this will be helpful... I'll be reading the mailing list, so if you
would like to ask for info, blame my hardware, or insult my style (it's late
in my timezone!), feel free.
Best wishes,

Hi,
I tried to reproduce this on my PIII-500 VIA chipset box and couldn't.
(problem doesn't seem to be generic fwiw)

Hmm... Well, I haven't succeeded in hanging 2.2.x this way... So the
hardware, (while likely flakey) works...
I'll try out another amd system of similar vintage (whose mb make I know!
;-), and see if I can't find anything more helpful/generic... (as well as
give speicifc mb info for this system, since it seems to be hw specific) I
was going to put 2.4 on it anyways, eventually... In the meantime, well, who
uses floppies, anyways? :-)
I really wish I knew enough about the kernel/fd and my c were good enough I
could do something more constructive... I feel mildly guilty promising to do
my best to expose someone else's bug... :-)
