Subjectpanic in reiserfs in 2.4.0-test10, BUG at highmem.c:220
Hello,

Having tried the 2.4.0-test9 patch of reiserfs under 2.4.0-test10 I got
the following panic (see kdb session below). I was running bonnie on it
over NFS and at the same time running tar xIf linux-2.4.0-test10.tar.bz2
locally.

Regards,
Tigran
