Is sysctl debug.debugger_on_panic set to 1? You should automatically land in ddb if that is set. I suppose it is, since you posted some back trace in an earlier mail. It also seems to be the default, at least in my FreeBSD-14 kernel.
I see ddb report about panic, but it's all. Keyboard doesn't work, and panic occurs before any disks are detected, so there is no space for crash dump.
AFAIK ddb has a command to generate a crash dump. But I can't easily check that :(
Yep, but console is dead & there are no disks for crash dump at this stage.
It seems like there's a major bug when no SD card is inserted and the driver is in the kernel. And a timing problem when a card is in the slot at boot time. Good to know that the module still works.
Yep, smoke tests for module (without inversion!) pass: I could mount R/W SD card with release image, mount FS, read and write files, unmount FS and eject card without panics and errors. I didn't try any high-load tests, though.
Difficult to debug without your laptop model in the hands of a developer.
It is "pretty common" (but old) Lenovo ThinkPad T540p. I could provide remote access to it, but it will not help for such low-level and early panic :-( -- // Lev Serebryakov _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
