Hello Andrew,
I found a little "hickup" in the mm kernel series since 2.6.21-rc2-mm1/mm2.
1.) appeared while boot (no VFS mounted at time)
BUG: at arch/i386/mm/highmem.c:61 kmap_atomic()

2.) some time after when I run some ups i hit this
BUG: atomic counter underflow at:
[<f94140a6>] [<f9414657>] [<c03d6611>] [<c03d4c85>] [<c04175c3>]

=======================
Then in 2.6.21-rc3-mm2
Now for rc3-mm2 the bug of under 1.) of rc2-mm1/mm2 gone.
But still here -> underflow..*huh*

[<b0102ba2>] [<b0400000>] =======================
Also I found some mis-beheviour of the Attansic "atl1 driver"
Maybe I address it wrong but I don't know (sure) who is the real maintainer.
Well I looked at atl1_main.c but to be honest there aren't obvious
information to whom/where I should address such issues.
Could you please so kind to address it to the right person?
atl1: hw csum wrong pkt_flag:1600, err_flag:80
All these hickups never appeared in the latest vanilla kernel
2.6.21-rc2 + even the last git-updates
2.6.21-rc3-git3 there is also not such behaviour
Thanks for your patience.
Best regards
Michael
