Subject: BUG: spinlock lockup while performing FS operations
Hi!
Faced with this problem. There are RAID5, assembled by mdadm (/dev/md127),
which is divided into 2 partitions (md127p1 and md127p2). In both reiserfs. The
second partition is exported via NFS. Everything works, the array is intact and
fully synchronized. SMART says disks are healthy. But when copy too many files
all hangs and saves only the reset. After a reset of course runs fsck, and then
synchronize the array.
I have a brand new computer. Sleaze is not set. Motherboard gigabyte 870-UD3,
Power Supply FSP 700W, memory 16Gb Kingston, CPU Phenom II X6 1090T.
I reported an error on bugs.gentoo.org: https://bugs.gentoo.org/show_bug.cgi?id=385047
Was compiling a custom kernel with support for debugging and debug messages are received.
Duane Griffin then sent me upstream.
Now I have have BUG spinlock lockup on screen:
