Bug#1057790: linux-image-6.5.0-5-amd64: deadlock on RTL8125 in jumbo mtu mode
Package: linux-image-6.5.0-5-amd64
Version: linux-image-6.5.0-5-amd64
Severity: important
Dear Maintainer,
My RTL8125 NIC stoped working after upgrading the kernel (linux-image-amd64) from version 6.5.10+1 to 6.5.13+1.
More specifically, the previous kernel that this meta package depends on (package linux-image-6.5.0-4-amd64) worked fine; but the new dependency (linux-image-6.5.0-5-amd64) causes my NIC to stop working.
I found this upstream bug report: https://bugzilla.kernel.org/show_bug.cgi?id=218187
And I can confirm that I'm also using a jumbo MTU (9000 bytes).
The issue has been fixed in kernel 6.6.5:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/net/ethernet/realtek?h=v6.6.5&id=a9ef897677f957401842e45f2006167cdf757ee4
But I'm not sure if kernel 6.5.x will still receive a fix, as it's EOL.
I added below two snippets from the syslog, illustrating the issue.
Cheers, Timo
