Hello,
[1.]
Token-ring memory crash with kernel 2.1 and 2.2
[2.]
We have some Linux systems PCI/SCSI, PCI/IDE, MCA/SCSI
all these systems have Token-ring adapters.
we have had this problem with all these systems in Linux 2.1 and 2.2
(no problem with the 2.0 kernel) for a long time,
the Systems crash while looping on the messages:

kmem_alloc: Bad Slab magic(corrupt) (name=size-128)
tr0: out of memory. frame dropped.
...

or with these messages:

CPU: 0
EIP: 0010:[<c011ea1c>]
EFLAGS: 00010086
eax:...

Code: 8b 69 08 81 fd 2b 2f c3 a5 0f 85 dd 00 00 00 8b 69 0c 85 ed
