当 Debian 10 正式发布时,我将我的 Debian 从第 9 版升级到第 10 版。自从我升级到 Debian 10 后,我在启动时收到以下消息:
[ 11.008027] pstore: Using compression: deflate
[ 11.008597] pstore: crypto_comp_decompress failed, ret = -22!
[ 11.008666] pstore: decompression failed: -22
[ 11.008784] pstore: crypto_comp_decompress failed, ret = -22!
[ 11.008845] pstore: decompression failed: -22
编辑/sys/fs/pstore
:按照评论和答案中的建议清除日志文件后,pstore:
消息现在消失了。但是来自的消息(如下所述)usb 1-1.5
仍然存在,这些消息在引导时花费了太多时间。
最近一些关于 USB 的消息也开始在启动时闪烁:
[ 91.875667] usb 1-1.5: new full-speed USB device number 81 using ehci-pci
[ 91.955706] usb 1-1.5: device descriptor read/64, error -32

[ 94.227687] usb 1-1.5: device not accepting address 84, error -32
[ 94.227912] usb 1-1-port5: unable to enumerate USB device
因此,这些decompression failed
和unable to enumerate USB device
消息在启动过程中被多次报告,因此需要更多时间才能到达登录屏幕。如何排除故障并消除这些消息以节省启动时间?
顺便说一句,系统看起来工作正常,没有任何问题,笔记本电脑的所有 USB 端口在启动后也工作正常。
