another 2.4.12 + aacraid + SuSE failure.

Using SGL (sorcerer.wox.org) Linux 2.4.13 + patches
It appears to be only for the ext2 FS's and not for the reiserfs.
Interesting, if you've compiled in kernel debugging & the SysReq key stuff,
and then issue an emergency sync (Alt-SysReq-S) it works to break the ext2
out of the lock.
An strace of a hanging e2fsck, hangs at the opening of the device...
I'll perhaps have to try the -ac patches then ...
