Today I downgraded my main computer to Buster 10.2 (current Stable) and found some problems.
First: Syslog is constantly filled with messages like these: xhci_hcd 0000:00:14.0: WARN Wrong bounce buffer write length: 630 != 318 xhci_hcd 0000:00:14.0: WARN Wrong bounce buffer write length: 234 != 0 xhci_hcd 0000:00:14.0: WARN Wrong bounce buffer write length: 284 != 630 xhci_hcd 0000:00:14.0: WARN Wrong bounce buffer write length: 208 != 284 xhci_hcd 0000:00:14.0: WARN Wrong bounce buffer write length: 386 != 234 Second: I suffer text console screen corruption when I press Ctrl-Alt-Fn, screenshot here: https://bugs.freedesktop.org/attachment.cgi?id=143903 It makes text console use very unpleasant. Graphics are Intel Corporation HD Graphics 530 (rev 06). I know these bugs have been solved in later kernels (I was in sid until yesterday) but since buster is tied to 4.19.0-6 I don't know how to preceed. Any ideas? Thanks in advance.
