Hi all! I'm not subscribed to the list, but got a crash this morning with the brand new 2.4.0-pre8. Hope it helps. BTW, thanks for your great work. J. Accot ------ [1.] One line summary of the problem: kernel BUG at ll_rw_blk.c:711 [2.] Full description of the problem/report: First, I typed 'sync' (remotely), which dumped core. I typed it a second time to see whether it could be reproduced, but the machine already crashed. The kernel log was: Sep 9 14:54:25 julee kernel: kernel BUG at ll_rw_blk.c:711!
