SubjectBUG REPORT: bug in eepro100.c driver
Hi!

I keep getting kernel panics with 2.4.21-pre4 (and 2.4.20). Here is the
kernel panic (I couldn't cut & paste in the datacenter, so I just wrote down
the stack trace):

------------< snip <------< snip <------< snip <------------
root@trillian:~/uni-qos# cat panic.txt
c0192eb1
c0176c8c
c017718c
c0176afa
c010810f
c01082b3
c0105240
c0105240
c0105240
c0105240
c0105263
c01052d2
c0105000
c0105027

0f 0b ef 04 e0 87 1e c0 f7 c5 00 04 00 00 74 36 b8 a5 c2 0f

EIP: 0010:c012642e
ESP: c0221eb4

KERNEL BUG slab.c:1263
root@trillian:~/uni-qos#
------------< snip <------< snip <------< snip <------------

A quick objdump through the kernel's vmlinux image reveals, that the stack
trace above looks as follows:

------------< snip <------< snip <------< snip <------------
c0192eb1 alloc_skb
c0176c8c speedo_refill_rx_buf
c017718c speedo_rx
c0176afa speedo_interrupt
c010810f handle_IRQ_event
c01082b3 do_IRQ
c0105240 default_idle
c0105240 default_idle
c0105240 default_idle
c0105240
c0105263 default_idle
c01052d2 cpu_idle
c0105000 rest_init
c0105027 rest_init
------------< snip <------< snip <------< snip <------------

It crashes when it hits BUG(); in slab.c:

------------< snip <------< snip <------< snip <------------
#if DEBUG
if (cachep->flags & SLAB_POISON)
if (kmem_check_poison_obj(cachep, objp))
BUG();
------------< snip <------< snip <------< snip <------------

Could somebody please tell me what is wrong here and how to fix this?
