Topic

Updated kernel packages that fix various bugs are now available for Red Hat Enterprise Linux 7.

Description

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following bugs:

• block mq hang of a blk_mq_freeze_queue_wait(), which waits for a zero of a q_usage_counter, which never happens (BZ#1824546)

• update qla2xxx driver with critical bug fixes (BZ#1832221)

• Emulex lpfc seems to get hung up failing IOCB'S continuously on kernel 3.10.0-957.21.3.el7.x86_64 leading to Oracle evictions (BZ#1835675)

• Possible race between scsi_remove_device() and scsi_probe_and_add_lun() code paths. (BZ#1836890)

• [Hyper-V] hv_netvsc performance issue in HyperV 2019 (BZ#1838600)

• revert the kernel patch "xfs: catch bad stripe alignment configurations" (BZ#1839697)
